    No Felix 🙂. I moved the blue spotted sunfish and Gambusia affinis out and moved in Gulf Coast Pygmy Sunfish in. The tank has gone pretty green which is perfect for raising baby pygmy sunfish but not so good for be able to see what is going on with the sunfish. Pygmy sunfish are just the sort a fish that would have been collected and kept if more exotic tropical fish were not available. But after the pygmy sunfish run their course, the next step will be to move in angelfish, zebras and swordtails and see if I can get the aquarium to look like this: I have got all 3 in holding tanks waiting for the Vallisneria to take off a little more. So far the val has been slow to grow. I might put a little dirt underneath the Vallisneria to see what happens.

    Brine Shrimp Direct

    I hatch the descapsulated brine shrimp eggs prior to feeding to my fish. Same nutritional value, just minus the shells.

    I don't rinse my baby brine shrimp. I believe the residual salts are beneficial to fish.

    Corydoras paleatus, the Peppered Corydoras, does fine in that temperature range.

    I was totally thinking about @Maggie every time my son mentioned the name. 🙂

    The rat keeping subculture is just as intense as the fishkeeping subculture. My youngest son and his girlfriend always have about 8 rats at any one time. The rats live about 3 years at the most so there are funerals from time to time. Today was one of those funerals and we buried Maggie in a garden bed this afternoon.

    Only chemical filtration needs to be turned off. Since your filter media is the gravel in your aquarium and it is only performing biological filtration you should leave your undergravel filter running just like it is. I would not recommend turning the powerheads off as that will not be good for the beneficial bacteria in your gravel.

    Not sure. I agree the 4" depth is what allows the oxygen free zone, but disturbing might be worse than just leaving it alone. I would be interested to hear what other people on this forum experiences were. In the past I have had deep substrate like you have and it never caused any trouble, but I also never tried to gravel vac it.

    It is very likely hydrogen sulfide. It is a product from the metabolism of anaerobic bacteria in the low oxygen part of your substrate. Some people are concerned about it, but I doubt you will ever experience it at levels that could be harmful to your fish.

    Everyone seems to be taking a break from breeding for the moment. The second pair to breed may have actually hatched their batch of eggs, but I never saw any wigglers after that. I wouldn't be surprised if it takes a month or two to get the first batch of babies.

    It has been moved to the General Forum.

    I am always looking for any differences in the 3 aquariums. I found one. The Dirt tank is the only one that has any staghorn algae. It isn't much but here it is. It looks worse in closeup, and I could get rid of it in heartbeat, but I am going to leave it and see what happens. That swordtail in the photo pecks at it all the time.

    The largest brood of guppy fry from a single birth event was 244. This was at the Shedd Aquarium in Chicago.

    The rule I follow is, if I wouldn't eat it after it thawed out, then I wouldn't feed it to the fish.

    Multi-Tank Syndrome (MTS) despite all the money poured in to hobby, and all pledges at the MTS telethon and we are still no closer to a cure than we were in 1930s.

    The picture above is Gertrude’s Spotted Blue Eye Rainbowfish, Pseudomugil gertrudae. One thing about rainbow fish is that there are a lot of different kinds! Just ask @Bob! There are several others that have a yellow coloration, including the Yellow Rainbow Fish, Melanotaenia herbertaxelrodi. and Pseudomugil furcatus, the Forktail Rainbow fish. I bet there are others too. And as far as reliability of Endler photos, I just took this photo. It is straight off of my iPhone.

    I add this (sparingly) to my tank of RODI water before I use the water in my aquariums.

    I needed some cherry shrimp and I was pretty sure some must have gone down the standpipe in the big tank out to the outdoor pool. It has been cold here recently so I had to bust through ice on the top to put a net in. Yep, cherry shrimp were outside, underneath ice and doing just fine.

    Caribsea Peace River with a little bit Caribsea Rio Grande beneath it, in the Nerm aquarium.

    It is an interesting problem. Substrate doesn't seem matter as sometimes my green water tanks are bare bottomed. The two consistent factors are fertilization (which can be both fish poop or additives) and strong light. The 3 tanks above have the same pH, ammonia, nitrite and nitrate according to the API Master test kit, even though Nerm get more fertilizer in the way of Root Tabs. All 3 get Easy Green and Easy Iron. Lighting is about 11 hours a day but growing shorter with each day. The Nerm tank gets the most fertilizer of the three aquariums and the greenest water. The 1930s tank stayed clear when it didn't get much sunlight. But once it got full sun all day, it turned green. And 1930s aquarium has inert creek gravel and doesn't get fertilized. That is clear as mud, right? One tank in the dirted tank project is green because is gets more fertilizer. Except for the fertilizer, all the tanks are identical, setup at the same time with same plants and are treated the same. But, the 1930s aquarium has green water, gets no fertilizer and wasn't green until it started get a lot more sunlight. And finally this aquarium was clear until I put started (over)feeding constantly. Once I cut back on the food, it cleared up. The problem with green water is you can never grow it when you want it and it grows when you don't want it. One thing for sure that will clean up green water in a heartbeat is Daphnia. Daphnia will clear water overnight. Cutting back on light clears it up also.

    When it is emersed it an obligate root feeder: Can it survive as only a (essentially) floating plant. I suspect so, but I have never tried it. It will likely attempt to grow some roots.

    Here is where I started: Here is where I am at as of today: + It must be the Root Tabs, as one surprise so far is how much better the Baby's Tears look in the Nerm tank. I couldn't fit all of them in the standard photo: Eco Baby's Tears: Dirt Baby's Tears: Nerm Baby's Tears: The lighting is the same in all 3 aquariums so that rules out lighting as a differential.

    Daphnia in the presence of fish develop something called 'phenotypic plasticity'. Which means factors given off by the fish effect the development of the Daphnia causing the next generation of Daphnia to grow spines. It makes the Daphnia less palatable to the fish. I don't know if that is what is happening with your Daphnia, but it does happen.

    There was a lot of substrate feeding in the big aquarium in addition to liquid fertilizer. You tank looks really good!
