compatible for a species tank

[shelby]

what fish would be a good one to put into a 3 1/2 ft tank with sailfin cory which are 3rd generation don't want any aggressive ones, at mo have got a community tank and a south american species tank. thought about doing a killifish only tank is that a good idea or a bad one.

I believe corys are fine with pretty much any non/semi-aggressive fish, so the choice is mostly up to you. If you like killifish, you should do some research and try that set up.

Go for it. Corys can go with just about anything.
