Hmm... at first blush, looks like two females to my eyes. Mature male Kribs tend to feature blue-white / line green-white pelvic fin colorations, where females display far more maroon on the pelvic fins.

Can you share a photo of both? The one pictured looks like a female.

Very kind of you. Saw someone asking about what to feed their young B. Rasboras, and thought to share this journal.

A while ago we were looking for a small schooling fish that would be fine staying up top in a 20 gal long as dither fish for a pair of Kribensis we wanted to spawn and see more of. Our LFS had some Brilliant Rasboras (Rasbora einthovenii) for sale. They were perfect for what we wanted. We raised several batches of Kribensis, and eventually needed to sell them all. They were hard to catch, so we drained the water low to get them all. Once we refilled the tank, the Brilliant Rasboras began to show spawning signs. So we added some more java moss . . . and, long story short, this took us on a fascinating adventure. We made a BAP Video journal series. If you're interested, this was a lot of fun. We learned a lot!

Stendkar discus may be more tolerant. Try Discus Hans over in Baltimore MD. Ask his view on your situation. Furthermore, maybe just buy a few juveniles and see how they do for you. Keep the tank hot... 85-88 degrees. Consider planting your tank well (choose plants that can handle heat), and add lots of wood. Maybe get an R.O. system, and just mix it with your tap water for changes? Look at Lowes to price them.

We just raised a batch of these for BAP. At that size, we found that Bug Bites flakes ground up very finely between fingers were readily eaten. We mix the Bug Bites Spirulina flakes with the red flakes (color enhancing).

Out of curiosity... is it common for female dwarf gouramis to display any vibrant coloration? We bought 4x females (specially ordered) from our LFS today. They’re more of a drab silver-gray.

The smaller one (pictured alive above) with rounded dorsal fin tip and more crimson belly is the female. In the photo with both fish in, the nearer one is the male. Females get aggressive when ready to spawn. Here’s a breeding journal video if you’re interested:

Green Terror is a great option. A large tank will be appreciated. Awesome video above from HenryC. Our LFS has a tank with a Green Terror. It's so personable, they refuse to sell him!

Looks good! Sounds like a plan. Catappa leaves are Indian Almond leaves - same thing. Take care with them. Our water is about pH 7.8 from the tap, but very soft. Too much Catappa leaves, and the breakdown produces humic acid which crashes pH. To be safe, maybe consider just letting them go and see if they like each other. Rainwater is usually very close to 7.0 pH, so that should be enough to trigger something. We usually just do 25% water changes with rain water. Another idea is to let water stand in a 4-5 gal bucket with catappa leaves or alder cones in to increase tannins. We even use rainwater drawn from our sump pump (always test that water first, of course). Then, when you add that water for a water change, the humic acid doesn't build up too much because the leaf litter is not breaking down _in_ the aquarium constantly, but rather in the _bucket_. We had a pair of wild-caught Apistogramma Bitaeniata spawn that way a few times. Here's a little video . . .

Beautiful planted aquarium set up! Cacatuoides are so charming. No really great answers here... just some food for thought: (1) if your male is a bit old, he may be an unwilling breeder (2) a healthy female Apisto will turn yellow, and lose certain markings when ready to spawn (3) female Apistos guarding eggs / fry are often the more aggressive ones... they will sometimes wind up and tail-whip the male (4) that hole in the Apisto hut may be too large... females prefer really small openings. You can probably plug off 1/2 that hut and interest her _more_ If we were breeding them, we’d definitely just let them go to town in the established tank. Depending on your water parameters, they may require some selective triggers to spawn. Try rainwater. (Maybe) Try adding a Catappa leaf. Feed live foods. Up the water changes. Give the female(s) 1-2 months to settle in. Consider also some “dither” fish. Pencil fish are always recommended... if they’ll take to your water. Good luck!!!

You might reach out to the AKA (American Killifish Association) via Facebook. Killi breeders are often interested in getting other fish keepers into keeping certain strains, since they are short-lived (though beautiful) fish. American Killifish Association M.FACEBOOK.COM American Killifish Association. 2.4K likes. The Official Facebook Home of the American Killifish Association... We are looking into getting an egg-filled mop from someone in our fish club soon. One note: be sure that you have a lid that completely covers your aquarium. Many killifish are serious jumpers!

That was my thought. It appears that fertilization for Hummingbird Tetras is internal... perhaps a bit different from other characins...

No professional answers here! Just enthusiastic amateur zeal for the hobby. These are absolutely gorgeous fish! Two followup thoughts: (1) can you find any collectors who can report on the in situ environmental factors where they are caught in the wild? (2) maybe reach out to Tannin Aquatics, and ask how he’d set up a tank for breeding them. He’s had genius success with spawning tetras in home aquaria over years past.

Lots of great responses above! If you're looking for another method, without using m. blue, here are a few videos explaining our process. These are journal entries for our BAP project. We're working on Corydoras Aeneus right now. Not master breeders of corys here! But this method is working for us. Lots of details . . . Video #1: Finding eggs and Pulling Video #2: Cory Eggs hatching Video #3: Fry growing Video #3: Cory fry entering Week 3 towards BAP

Silvertip Tetras, I presume? Their eggs are so small . . . how did you find the eggs? How did you catch them? Spawning mop? Curious what other fish you have in there? Any photos?

We prepared a series of video journal entries for our Fish Club to submit for BAP - breeding Koi Angelfish (Pterophyllum scalare). If you're new to breeding angelfish, and want to watch a process that has worked for someone, these videos may be helpful. Let us know if you're successful raising up Angelfish this way!

We have a koi pair that is happy in a 20 gal. long. They spawn every 1-2 weeks. If your adults are really large, they may need a 20-tall. We lean a piece of slate against the side, and then remove and hatch out in a separate specimen container.

The Spawning tank is a 29 gal. Large HOB Filter plus small sponge filter. Weekly water changes. Tap water (town / city water) is 7.8 from the tap, but fairly soft. GH ca. 90 ppm. KH cal 30 ppm. In the planted tank with wood, pH tends to drop down to 7.5 pH. We keep the temperature high largely due to the young Discus we also keep in this aquarium - 82-degrees Fahrenheit (28-Cel). Here is a copy of the BAP report we submitted to our fish club (PVAS) for an earlier batch of Rams raised in this tank. This report was actually for the _parents_ of these adults in this series. Some of the details for the more recent batch are altered, but a lot is the same. __________________________________________________ PVAS BAP SPAWNING REPORT 19 October 2019 SPECIES Mikrogeophagus Ramirezi German Blue Ram (Electric Blue Male & Golden Female) REPRODUCTION Method of Reproduction: Egg Layer Number and Gender Distribution of Parents: 1 Male (Electric Blue), 1 Female (Golden) Pair Origin of Parents: LFS (source unknown) Approximate number of fry: Originally hatched ca. 75 Date of Birth: Free Swimming 18 September 2019 Approx.

Our first attempt last year ended in failure. But then we were able to raise 7 fry from a second batch to maturity. One major goal has been to raise a BAP viable batch of 10 or more. In brief, we set up the decor so that the rams will spawn on a small rock which is then removed to a separate container with a suspended air stone to “tumble” the water over the eggs. Between 1/2 to 1 ml. of Hydrogen Peroxide (H2O2) is added 1x every 12 hours, for just two doses to fight off fungus. The fry hatch in ca. 2-3 days, seen as wigglers. Once they eat through their yolk sack and are free-swimming, the challenge begins. Sometimes a male does not properly fertilize the eggs. Another time the eggs were laid in an area too difficult to “pull” in order to hatch. With this pair - an Electric Blue Male, and a Golden Female - their first batch did not survive past three weeks. We tried feeding on hard-boiled egg-yolk and Sera micron, but without an early transition to live food, they did not grow properly. With this (submitted) batch, we determined to move them over to baby brine shrimp earlier. This has made all of the difference in survival rate. Furthermore, we have since been able to successfully move more batches over the two-week threshold with this feeding plan. We feed the rams 2x / day, feeding BBS and a light dose of Sera-Micron mixed in water. Daily vigilance is essential with Ram fry. We carefully siphon off all waste and uneaten food off the bottom, and draw out 50% of the container water. This is replaced by R.O. water that has been suspended in the tank to reach tank-temperature (ca. 81 degrees Fahrenheit). We plan to transition these small fry first to a “well-seasoned” 5.5. gal aquarium containing a fair amount of algae and plants to grow out for a month or so. From there, we have a 20 gallon long that will be the larger ram-colony grow out tank until the rams are ready to be culled, moved on to our LFS, or selected for ongoing breeding projects. Three other batches were also grown in this period. Another small one from the same parents had only 6 fry survive. Two other batches from 2nd generation GBR born in our water had 4 fry and ca. 50 fry respectively. Apart from the first few days where fry are free swimming and need food that they can consume, the crucial time frame for survival is the 2-3 week point. In this period, the rams tend to crash with just a few survivors — or en masse — they tend to press through and survive as a larger group. Water quality is crucial, as any buildup of Ammonia or Nitrate leads to early fatalities. It is difficult to keep the containers fully cycled with this approach. Nitrite tends to read higher than preferable. In the future, we plan to implement micro-sponge filters in the Specimen Containers to cycle them once the fry are large enough to avoid being hurt.

There are a number of factors to consider. We have 2x LFS and one chain store. Big store is prevented from buying locally raised fish from corporate. One of our LFS will offer store credit. The other will pay in cash outright. But we built those relationships by patience, and spending plenty of money over several years. Guppies go for $0.25 - $1.00 / each depending on strain. Platys sell for less. German Blue Rams sell for $2.50 each. Electric Blue Acaras will get about $3.00 each. Ancistrus might get $1.00-2.00 each, depending on their size. The economy in your area is key, as well as what kind of fishkeepers are buying. Also, pay attention to what’s going well and what’s struggling. Our home-raised guppies lasted, but every imported guppy died in days. So... we got about $100 for as many guppies recently. But no one in our area is buying discus. The store just can’t sell them, since there are few experienced freshwater aquarists near us.

Everyone likes seafood!

In our most recent batch of angel fry, we pulled the eggs and hatched out separately. Their growth was inconsistent - some growing much faster - "runners" - and we were appalled to come by their grout tank to witness exactly what others here are describing, larger fry massacring smaller fry. And ours were from the same batch!

Interesting! Ok. Our mature males have not never turned white. In the case of the fry, I guess we're back to square one.

We hatch ours daily out of a 16 oz. can sourced from brine shrimp direct. See photo. Keep the eggs refrigerated. Those silly little vials were very costly.

Had similar question and observations. One of our adult females always turned pale in the head and body when ready to spawn. Now, with all of our fry, we can go through and easily pick out the females due to this same discoloration. I think it's a female thing, not a disease. Perhaps the pheromones released by one in spawning mood affect the others? We have about 25-30 in a tank growing out. Easy to see who the guys and gals are.
