Finally I have something to update. Earlier in the year we got a bigger custom aquarium made and moved out all of the fish into that, apart from the snakehead pair. We took out the tree log and some of the plants and then left it to go swampy with no water changes to mimic summer in their natural habitat. Earlier in winter they had temperatures down to 18C and big water changes in spring.
We saw them courting but no eggs or fry showed up. They're not supposed to need a cave but we thought that they liked the tree stump cave before so put in some black sponge leaning against the side to make a basic cave. It's the same sponge used to baffle the filter intake. They seemed to have been waiting for a cave.
Just over 2 weeks ago, Big Boy, the male had disappeared into the sponge cave and after a day or so we spotted a couple of tiny fry when he popped his head out. They were at the 2mm long, translucent white blob with a tiny tail stage. The female has been staying near. She lays eggs for them to eat and guards them.
By 6 days old, the fry were about 4mm long and darker in colour. We could occasionally see a few bouncing about on the sand/gravel.
By 8 days they were about 5-6mm and their dad had moved them out to a patch of floor near the outside edge of the sponge "wall". They were better at bouncing around with some small stretches of actual swimming. If they got too far then he would pick them up in his mouth and bring them back. They pop out of his gills.
By 12 days they were about 6-7mm. Able to swim properly. Dad had taken them to a spot near the surface. They can be seen picking at plants and sponge, eating tiny inverts I assume. We have been adding a bit of hikari fry dust and a smidge of baby brine shrimp too. They have fat tummies at all times.
Interestingly the female also picks them up and takes them back to Dad. I have never noticed this mentioned in other breeding accounts. The fry surf over and sit on both parents. They also peck at them, maybe eating slime coat?
By 13 days the biggest is about 7mm. You can see their little pectoral fins frantically flapping.
Here is a fry facing forward. Sorry about the poor quality.
They are about 14 days old today. Hopefully they will keep on growing with no problems. I can't tell how many there are. We've only seen 5 at once so maybe they lost a lot of them while they were tiny.

Nice video. I'm very envious of your rainbow darters.

do you need to have a constant supply of live food in there tank like you do with seahorses
They can go overnight or a few hours in the day without food so they don't need a constant supply but very regular feeding is required because like seahorses, they have no fat reserves. They do actually eat frozen cyclops which is handy as a backup food.

I did get them on frozen daphnia and cyclops though. Certainly a fish I might reconsider down the road. Be very curios on how your breeding project goes.
They're definitely on the high maintenance end with their food needs. It will be nerve wracking trying to keep the fry fed if they do ever breed.

Wow, those are neat! It's funny to see how the shrimp boldly walk up.
The blue dream shrimp ride them occasionally!

They do. Often they sit in the plants in a vertical position and hold on with their tail.

I thought that maybe some people might be interested to see my freshwater pipefish Doryichthys martensii.
I'd also be interested to hear from anyone keeping these or similar species. Has anyone bred them? Apparently it's not too difficult with some species. They're like sea horses so the male takes the eggs from the female and holds them in a pouch until they hatch.
These guys are also known as long shouted Pipefish and they come from Southeast Asia. They're true freshwater fish unlike many that are estuarine or fully saltwater.
I have 5 in a 50l tank because they enjoy company. They're not quite full grown yet (assuming 15cm full size) so I might upgrade them but for now the tank works well because they don't move much or fast and they require mostly live small foods. The smaller tank size makes it easier to get the food to them. I have neocaridina shrimp and amano shrimp with them as an extra food source. They will pick eggs straight off the amano shrimp, it's quite funny to see.
Here's a video of them being useless at hunting daphnia. I like how they move their eyes. It reminds me of puffer fish.

Changing the substrate should not hurt your beneficial bacteria population very much. I saw a study that showed that the vast majority of them are found in the filter. You can always feed a bit more lightly for a few days after you change it if you're worried.
As for how to change it, that depends on your tank setup. There should be some helpful videos on YouTube to give you some ideas.

I would put at least 20 CPDs in that tank. I just checked the size of my 45l in US gallons (why can't you people use normal gallons or litres? 😜) It's just under 12 US gallons and I have 16 CPDs in there plus a few other fish, 4 horned nerites, 5 amano shrimp that I am growing out and a blue dream shrimp colony. Heavily planted and I do a small water change every 3-4 weeks with no nitrate problems. I started off with 8 CPDs but they're much happier now there are more.
I agree with the others that you probably want to reduce the oto count.

I have a leopard frog plec with 3 Gastromyzon ctenocephalus in one 105l tank and a red bristlenose plec with 2 Sewellia lineolata in a 210l. Never had any problems in either thank.

@Daniel Love the sunfish! 🐟
Decades ago, Carolina Biological used to sell Three-Spined Sticklebacks, the N.A. fish that builds a little nest to house their eggs. I wish I had tried to start a colony of them. I believe now, they may be listed as endangered.
I had seen Americans mentioning three spines sticklebacks but I hadn't looked up to see if it's the same species as we get in Europe. Turns out it is! I love watching these in the wild and have always wanted to keep some in an aquarium but there supposed to be quite tricky to keep.

Mine is out and about a lot too and doesn’t seem skittish at all. I have her on a sandy substrate so she could bury herself if she want but there are plants and hiding places under rocks. Her favorite place to get away from it all is a tube I buried under some rocks.
What size are your carnivore pellets? I have Hikari Sinking wafers but they are hard initially and are about 5 mm wide. I am looking for something smaller that sinks and smells good to them. She gets mostly live black worms, frozen brine shrimp or blood worms.
Maybe they're not as reclusive as people make out. I think that it's the Hikari wafers that I use. I often break them up before dropping them in. He can worry a soft whole one enough to eat it now but pieces are easier.

May I ask, what do you feed your eel and does he pretty much compete well with the others in order to eat enough?
This is my second one. I didn’t know enough about them when I had the first one (and not as many foods were available to me at the time). I don’t want to over feed but I realize that they are slower foragers and have had to remove some fish because they would eat it all before she would enough.
From what I have read about them, I think that mine might be a weirdo. When he (or she) first arrived it was only about 7cm long and maybe 1cm wide. It was in quarantine with the Rhinogobius gobies that I got at the same time so I would put in live daphnia for all of them and after a couple of days got the eel to eat live and then frozen bloodworms from tongs. It was so tiny and slow that I don't think it could compete with the gobies. Now he's bigger he'll swim out to the middle of the tank and eat with all the others. He'll eat frozen bloodworms, frozen krill flakes, tetra crisps and sinking carnivore pellets.
I don't think that it's normal for them to be so out and about. It's not like mine couldn't stay buried in the sand or hide in the plants if it wanted to though.
If yours is a bit slow then getting them to feed from the tongs or your fingers is a good idea to make sure that they get fed. Another thing that some people do is put food in a container that only the eel can reach into but I am not sure that would work with your tank mates. I hope that your little guy thrives 😊

"Eclectic stocking" is a great name for it. 😁 As long as they all get along it's all good.
Macrognathus eels are such great little characters. The wiggly nose thing makes them so silly. They're like muppets.

How cool to see! And the fry instantly darted for cover and she looked to see where he went but missed him!😅
I see you have a Peacock eel in with them. What else do you stock in this tank?
The fry were very good at survival. I protected some in a breeder net but others stayed in the main tank and hid in the plants. I don't think that any got eaten.
The eel named Tiny Eel is a Lesser spiny Eel, he's growing out in there before moving on to a bigger tank. I also have a female T bar cichlid, 6 Pseudomugil luminatus, a few small gobies, hillstream loaches, otos, a banjo catfish and a leopard frog plec. I am terrible at doing the one centerpiece fish and a shoal of something smaller thing! 😆
The C. lateralis adults do well with everything. Their fry once they got to about 3cm were nippy little devils.

Very, very cool! I’ve never seen or heard of these live bearers before. I think they’re a good looking fish.
They're critically endangered in the wild which is sad. They're easy enough to breed but still quite rare in the hobby, in the UK at least. I was considering trying to get a proper breeding project going with them but none of my local fish shops are interested in taking any so I have to sell privately which is a pain in the bum.

I have a pair of Characodon lateralis los berros that are collectively known to me as Tangelina. They're my favourite livebearer that I have owned because they seem to he much more intelligent and have more character and interesting behaviours than guppies or platies.
I have had them for nearly a year and the other day my husband pointed out that you can see their teeth!
I don't have anything other than a phone camera but I thought it might be interesting for people interested in livebearers to see a few pics.
This is Angelina aka The Great White Shark and her unfortunate looking face.
Here's Teabag the male. He changes colour a lot. No dark stripe here so I think he was displaying.
Last year I got a video of the female dropping fry. They're huge!

Do you know how hard your water is? It might be possible to look it up on your water suppliers website.
Water hardness can be very important for certain fish species and it's much easier to match the fish to your water than to change it.
There are definitely many easy to care for cichlid species. Are you only in certain ones? Depending on your water hardness you could do a community tank with a single Cryptoheros sajica, or a pair of kribensis or Apistogramma, for example.

I have a group of Red chinned panchax in my 105l community tank. They mostly stay near the surface and it's fun to watch the males spar with each other. These are easy to breed. Mine spawned in the quarantine tub and a few days after I took the adults out I saw tiny fry. They grew on hikari first bites. I had so many I had to feed some to my snakeheads.
I also have a pair of Fundulopanchax sjoestedti aka blue gularis killifish. The males looks fantastic but I get the impression that he is a complete moron. The female is fat and pink and eats everything. They're fine with large corydoras and Indian glass fish as tank mates.

Plants and some other fish and shrimp.

I've not kept them but have some similar species of killi and have researched them.
They're a colour morph of Aplocheilus lineatus. They're pretty easy to keep, not picky about water conditions. They get to about 10cm and are carnivores so don't put them in with small fish like neons or they'll eat them.
I think that you're best off with just one or if you have the space, a group to spread out aggression.
If you like the shape but want something smaller for the top of the water then red chinned panchax Epiplatys dageti are nice.
-
Big boy managed to lose all of the fry. He was too busy menacing the completely oblivious corydoras 😆
I might eventually put them in their own tank to breed them. I'm not too worried for now.

It's so satisfying seeing algae get cleaned up.

So fascinating! How large do they grow?
They generally max out at 11cm (not including the tail fin). They are small enough to bite a finger and it doesn't hurt 😁

Just caught up with this. Well done with getting them so far. I hope that they're still growing well.

Oh great! One more species of fish I now want to keep but can't! HAHA.
Absolutely beautiful fish, @Pigeonduck. Thank you for sharing and looking forward to more updates and photos.
I mostly seem to have invertebrates that I want to keep but can't. I remember discovering the fresh water pom pom crab. Decided that it sounded perfect and then discovered that they had been banned ☹
The same happened with the Mexican dwarf crayfish!
I'm glad that you find my silly fish interesting. I need to try to get a good video of Fat Cow jumping for food. She's like a sausage-shaped salmon 😆

Wild Mudskippers in Malaysia
in General Discussion
Posted
A retired friend of mine is still into wildlife photography and videos (it used to be his job) and his latest video is of wildlife in a mangrove forest in Malaysia. Near the start there are fiddler crabs and then a section with two species of mudskipper. Smaller blue ones and giant mudskippers that want to eat the smaller ones. I don't remember seeing the exact behaviours on any wildlife documentary so I thought that people might find it interesting. It's also a handy look at the habitat for people like me who want to one day keep mudskippers. He doesn't make any money from YouTube so I hope it's ok to share.
