Can these fish be together

[tjmortenson]

Ok, so my 30 gallon tank finnished cycling a couple weeks ago. I have a small bluegill sunfish and a rainbow shark right now, and I am getting an angelfish. Can I keep 4 glass catfish with them or will the cats get eaten?
Ohh and btw I know I shouldn't have a bluegill in this tank, I plan on upgrading to a larger tank when it gets bigger.

You shouldn't keep the rainbow shark in there, either. It's going to grow to be half a foot long, as will the sunfish.

The bluegill will likely eat the glass cats. They get very large and don't do well with most tropicals.

Hello and welcome to AA

Rainbow sharks need a minimum of 55 gals. Glass cats will most likely always be hiding if you keep less than 6. The shark will grow pretty quickly. If you can't upgrade to a 55 gal within 6 months I would rehome the shark.
