community fish tank
so we have this old 92 gallon fish tank and would like a little community fish tank. when i say community, i don't mean everyone in the block shares the fish tank, rather it's a tank of 'community' (friendly, co-existing) fish.
when they were on sale, we got about 20-30 of the neon tetras and a bunch of other small peaceful fish with various colors. then i saw some bala sharks on sale. we bought 6 of them after reading that they were community fish. since then, 1 has decided to jump out of the tank and commit suicide leaving 5.
but lately, i've taken the time to sit and observe the tank and noticed that the sharks are about 5 inches long now and most of the other fish are gone. no bones, no nothing. heck even the 4 sucker fish are gone too.
so what i'm wondering is if the sharks are actually eating the other fish and if anyone else here has seen this happen? we do happen to have a thai black sword fish. looks like an eel with it's ghostly fins on bottom, a yellow stripe down it's head and 2 yellow rings on its tail. that's sword fish is not a community fish, but it doesn't seem likely to be the culprit.
any suggestions please before i have to give away the bala sharks?
thanks
