Can anyone tell me how many eggs you would expect a 1-2 year-old Diamond Tetra to lay? The first surprise breeding left us with 9 live babies. The next time we found six. We just intentionally bred a pair in a separate tank and think that we have 10-15 possible eggs. We are guessing at what the eggs look like (small white specks) based on the fact that I had just bleached the plant matter before putting it in the tank. Mating them has been surprisingly easy. It seems that warming the tank from 75 to 81F and setting the light cycle to a continuous 12 hours was all it took the first time. This time, doing it deliberately, we set the temperature at 78 (I am having issues with my heaters and couldn't land the 81F), put the fattest female off by herself for a few days then added the slowest male that we got lucky enough to catch. They acted stressed for around 20 minutes until I added a freshly cleaned bushy plant, then they went at it for a couple of hours and we saw around 6 specks on the leaves. Since the eggs are supposed to take a few days to swell and hatch, we left the fish together for three days and have a few more specks to report. They did not appear to eat anything that we identified as a possible egg (probably waiting for them to hatch and wiggle). We shall see what happens. Caution: avoid using a particularly spiky plant in the main tank if you are not using a separate breeding tank. We lost a mother that way when she dove into the plant to eat the live babies and got stuck. The one they seem to like has little heart shaped leaves. Go figure.

    That's some great info on breeding these fish. I tried to find a resource that gave their clutch size. Basically all I have found is that Characins from the Amazon average between 30-60 eggs. Characins do start eating their eggs as soon as they are done scattering them about, so that could account for why your are seeing 10-15.

I have seen diamond tetras in my local aquarium and think they are mesmerising. I have a 90L tank with six corydora leopards, four otocinclus and two rams. Would five or six diamond tetras be okay with my other fish and would they be okay with my two rams?

    I have kept diamond tetras, and they truly are mesmorizing! I don't see any problem with your fish mix, and your tank is definitely large enough to house them. You didn't mention if you have any decor, but plants will also help with the mix, providing places for retreat as well as psychological comfort.

I have nine Diamond Tetra's and they are my favourite fish of all time, they are just beautiful to look at in the tank. I am so proud of them, they have bred in my Community Tank and I had four Fry survive from the breeding. To this day the fry have grown up to healthy Diamond Tetra's the First fry that I saw in the tank is now a Beautiful Male with long flowing fins' the other three born a little later are coming along very well. When I go up to my Community Tank it is always them that come up to me too say hello, my other tetra's are not as friendly. Yes the Diamond Tetra is my Favourite Fish and I hope they breed again, they are Lovely Fish.

I have a 55 gal with 3 diamond tetras, 4 red tetras, 2 catfish and a silver shark. When I was feeding the fish this morning I noticed one of my diamond tetras was spinning around in the tank. The fish ate when fed, but continue to spin. It looks cool to watch, but has me worried. Is it suppose to act like that or is something wrong?

    It may be a kidney issue. The kidney balloons up making it unable for the fish to fully control it's movements. Some fish do recover, but most don't. It is probably going to die though if you have a silver shark, they will nip at them when floating around until dead. Put that fish in a quarantine tank, that may help...

I have a guppy, molly, and colored skirt tetra in a 20 gallon tank. I'm ready for more fish, I want diamonds but I am worried about the compatability between them and the guppy. Is it OK to mix these two? Thanks in advance.

    Should be just fine.  They do however do best in groups of 5 or more.

Hey- Today is Tuesday and I got my first tank on Saturday. The fish came on Sunday, 2 of them being diamond tetras. We were told that these fish would be OK with the other choices of fish we had(4). But, this morning, one of the diamond's was found dead on the bottom of the tank. Since we got them into the tank, they haven't really eaten, been active, or swam forcefully. They just kind of lag around and float in a pair. We need to know why!! We can't get any more until the Nitrogen Cycle ends, but we would like to know if getting more diamond's is a good choice based on what happened 2 days after getting them.

    Diamonds are a fine choice but I wouldn't add anything until the nitrogen cycle is fully working. I highly recommend fishless cycling. It's really easy with a test kit, a bottle of ammonia, and some time.

    I think your problem would be putting fish in the tank too soon. You should let the tank cycle, without any fish, for at least a couple weeks.

    Tank should be cycled a bit longer before adding any fish. Mollies are always a good fish to cycle with.

I got a few of these by accident in a large group of Lemon Tetras. Now I buy them on purpose! They are really lovely fish when full grown and even stand up to my bully Angelfish and Pakistani loaches. Everyone asks what they are since they flash and sparkle gold, violet, and green.

Hello! I just bought two of these beauties and aren't sure how to tell if they're male or female.

I bought three (all they had) of these tetras a few days ago to go into my planted 32 gal. fully [fishless] cycled tank. Luckily they happened to be almost fully grown which is apparently when they show there true beauty.I can't describe how thrilled and elated I am to have gotten them. They settled in right away as if to say 'ok so what's there to eat around here'? They are hillarious to watch, with their funny and interesting antics. One minute swimming together as best buds, then sneaking up on each other for a suprise joust.So entertaining and so much facsinating personality. Never really agressive, just goofy and leaves other fish alone, even my tiny neons. They'll eat anything. And their beauty is astounding! They look like they were dipped in some craft sparkles, LOL. I'm going to get more to make a bigger school!! I HIGHLY recommend these fish.
