Today i got six small rummynose tetras to add to my tank. I came home later on to find this:
i've isolated the rest of the tetra's. this is the first time i've had this sort of problem with my bala, who is about medium sized.
anyway, i've overall been having compatibility problems in my tank, and would like some advice.
i have a few corydoras (i've lost a lot of these lately)
the bala shark
a medium sized featherfin catfish (who i was advised today might be responsible for the cory's)
a golden eeltail catfish
a few neon tetra's (never been attacked by my bala to date)
and a small whiptail catfish
[my tank is 3 foot]
when i find the dead cory's, they are either just a skeleton or seem to be missing their outer layer of skin...
any advice on how to better stock my tank would be appreciated
