Tiger barb died

I now only have 3 barbs, I don't know what happened. They aren't sick and the fish tank is perfect, Water and everything. My room mate noticed that one of them were floating and dead, i haven't had them for 3 months I was hoping to breed them in the future but now i have to go out and buy more. It sucks because it was one of my females, now i have 2 males and 1 female. I need to buy more fish for the tank anyways cause all i have are the Tiger barbs and 2 pleco's. Which i may breed if one ends up being a male and one a female, not sure how you can tell on a regular pleco and they have a long way to go for sexual maturity they are about 3 inches long each.

Anyways yeah, im kinda sad about the fish. I really liked the one that died, I trained it to
come to the top when i said fishy.


I want to note; i hadn't noticed because it was stuck behind this black thing that I have in the tank. The people i bought the 60 gal from previously had a salt water tank and i can't get it off or it'll break my tank. I don't generally look around there but now ill start incase another fish dies.

Sorry to hear about your loss.

Thank you.

Nothing else has died, which is why i find it strange. Maybe its cause i bought an old fish or the other fish were messing with it.

I will :) We got paid today so I might go down to the pet store and buy some more today if not then tomorrow.

Sorry to hear about your loss.

:0( hope nothing else happens.
