who ate my danios tails?
Hi There - I just came home and found one dwarf gourami dead already decomposed and 3 zebra danios with little or no tails - The tank has gouramis tetras and mostly little passive fish - we put in 2 larger more muscled fish a few weeks ago but they just stay in the corner away from all the others and hardly come out to eat at all - now this! could it be that the fish are not getting enough food and are eating each other due to hunger.

I would be curious to know just what those "two new muscle fish are"?

yeah... what kate says... you really can't just blindly toss fish into the same tank and hope everyone gets along. you actually can't even listen to the people at the petstore and assume they'll give you good advice. i would urge you to research the needs of the fish you have, particularly the new additions... and see if they have any aggressive tendencies. you might've tossed a couple oscars in with your tetras and danios, for all we know...  |

thanks for replying - I cant recall their name - the dope at the fish shop assured me they are not predators but they are bigger and stronger and faster than anything else in the tank by a mile - there is a pic of them in the avatar of member tfa101 perhaps yopu know what they are my other fish are:
2 black and white zebra danios
2 red zebra danios
2 yellow zebra danios
4 white skirt painted tetras 2pink/2 blue
3 gold gouramis
2 dwarf gouramis
2 red line torpedo barbs
3 other tetras

that looks like a shark to me, and i've never kept red tailed sharks, so hopefully someone else will offer input on that.... also, your gouramis could be a problem... if you have multiple males, they tend to not like each other.
tetras, barbs and danios are schooling fish, and like around 6 or so of their own kind... i'm not familiar with red line torpedo barbs specifically, but many barbs tend to be fin nippers - yours might be likely candidates, since there are only 2 of them and they don't have others of their own kind to chase, etc.

Hi there - are you suggesting that the gouramis and barbs could have eaten off the entire tails of other fish? - I have 2 danios with no tail left at all! Why are they doing this? For the last few months they have been living happily together - could it be too little food?

i'm saying that i see potential compatibility problems. whether the culprit is the territorial male gouramis, or the result of lonely barbs, or possibly even the new red-tailed sharks - i can't say for certain. compatibility problems do sometimes spring up suddenly - so it's hard to say definitively who's to blame.
my first suggestion would be to go to the species forums here, and find one for sharks, red tails in particular. make sure that's what you have, and read about their needs and behavior, and determine from that if you think they're the meanies.
my second suggestion would be to get a tank divider or something of that sort to keep the injured fish safe until you figure out what the problem is.
my third suggestion would be to ask here about vitamin supplements/slimecoat additives or whatnot to help them recover.
good luck. =)

i just read a description of rainbows (who grow up to 7", btw) and it describes them as 'scrappy', with a tendency to go after smaller fish...
i'd guess from that who the culprits are. =)

Yes they are redtailed sharks but not black - a very pale blue colour and very strong.
I guess i'll take them back to the fish shop - sadly - they are my favourite fish so far - but too big for the rest of them!
Thanks for the info
The strange thing is that the rainbows stay in their corner never get close to the other fish wheras the gouramis are very aggressive with each other and the other species - but there were no fish minus their tails untill the sharks came along - si I guess it is the sharks.

the ones with the grey bodies like that are called rainbow sharks, the ones with black bodies and red tails are red-tail sharks... i think the red-tail sharks stay smaller, but haven't read about their aggressiveness i would assume it's similar.
they could be nocturnal (i have nfi) but just because you don't see it happen, doesn't mean it isn't...

Hey.. sorry to hear about the Danios & Gourami. Yea, I'd agree that the sharks took them out.  The Danios who lost their tails could be treated by doing extra water changes and treating them with any of these: vita-chem, fish protector, stress coat. |

What could have happened is maybe, your gouramis who really aren't supposed to be together, they will fight to the death over territory. possibly started bugging your sharks, your sharks probably put up with it so long, then retaliated... just a guess... I don't own sharks but have a little experience with Gouramis.

I saw one of those at the LFS. It looks like an albino red tail shark.
That can be the culprit in your tank.
