    They are nearly transparent when they have just been released, and will hatch after 22-30 hours. It will take the fry 3-4 days to become free swimming.

Hey I have a 20 gallon with 5 black skirt tetras, 1 shubunkin goldfish, two bumble bee platies, 1 Bala Shark, 2 plecos, 1 guppy, 1 Cichlid, and 3 tiger barbs. My fish are very good together. The only problem I have is that My tetras aren't eating and I've only had them a day... Is that normal for them not to eat the first couple days?

    I would say it is not normal unless they are uncomfortable for some reason. Check the temperature and do partial water changes if there is any presence of ammonia or nitrites until the biological filter is functioning.

    The tiger barbs are probably stressing them

    Yeah they need to be kept in groups of at least six. If the cichlid is from Africa it could also stressing them out

Quick question. Ok, I have eight black skirt tetras in a 20 gallon long aquarium, along with four 3-lined corydoras and a mystery snail. One of my black skirts is a lot bigger than the others, but I bought them all together about a week ago (the tetras). Anyhow, this morning there are 5 of the smaller ones that are constantly swarming the bigger one. Is this normal for them? Should I be worried for the big one?

    You could try tasty treats like brine shrimp or bloodworms. They come in freeze-dried or frozen varieties. Otherwise, check for abmormal behavior like gasping at the surface, white spots on the fish, darting about the aquarium etc. These are signs of bad tank conditions or disease.

    Is this a new tank set up?  I would get a water tester and a filter.  Water conditions as a tank cycles will greatly affect a fish.

Can I put Black Tetras with Green Barbs? I have 3 Green Barbs and do not want to get more. My tank is only a 15 gallons. What fish can I put with these Barbs?

    Barbs and larger tetras will normally do ok together depending on size. Barbs tend to be a bit dominate if larger. Gaint Danios and platys are normal great additions. Can also put in catfish. Anything fast moving in usually ok. No angels or gouramis. Be careful not to over crowd your tank. Barbs like to be in schools so I would probably add a couple more.

Black Tetras are superb fish for newbies, but they are also excellent fish for the best of display tanks. I have a large school of them in a 300 gallon show tank in our living room; they are heavenly and get along great with the other community fish within the tank (i.e., Glowlight Tetras, Bloodfins, Buenos Aires Tetras, Red Glass Barbs, and Flame Tetras). I've had gorgeous Discus fish and Angel fish for years, in the show tank... but the masses of Black Tetras and other fish are just as beautiful, in their own way! I've had tropical fish since my grade school years; I'm now around 60 years old... and I know top quality fish when I see them. These pert, black beauties may be common and inexpensive... but as Walt Whitman sagaciously suggested... some of the best things in life are free. These fish, like flat miniature versions of Silver Dollars, carry themselves well, looking like content butterflies. They are never aggressive when kept in larger groups. They are very hardy and stay out at the front of the tank, displaying well. I even have a picture of one for the wallpaper for my computer!

I have two black-skirt tetras in a ten gallon tank. These fish were kept with three danios (two long finned), two ghost shrimp, an ADF, and one chinese alge eater. These tetras DO NOT like long-finned fish. It nipped at my betta's tail when he was in the tank, and had recently killed one of my danios, I give the other one till the morning... his fin has been nipped at and is frayed from the ends. The small finned danio is fine. Also the chinese alge eater loves them. They are great fish to keep, i just suggest that you try not to add new fish, nor put them with long-tailed fish.

    Well if your danios are slow, they will be attacked. I've researched a lot of fish and the Black Tetra will nip at slow moving fish and acts aggressively towards them. Be careful.

    Add a compatible tropical fish. Add in even numbers. Not in odd!!

Are they supposed to change colors? One minute their lower fin will be black and the next clear it's kinda cool and sometimes their stripes disappear.

    Out of my understanding they will lose only the black skirt. I have heard. I never heard of them losing there stripes this is probably a cause of stress.

    Did yours lose its stripes yet?

    plz write me back asap

    It's normal for fish of all species to appear to 'change colors'. They can, in fact, however this could be due to reflection and other factors.
