I have a preliminary listing of fish to add to the tank. I know they are semi or more aggressive, so I'm hoping that keeping them all way will cut down on any problems. The fish store seems to think they will get along well enough:
3 - Odessa Barbs (I have these now)
4 - Tiger Barbs
1 - Rainbow Shark
1 - Placo
1 - Snow flake eel
1 - Bichir
4 - Puffer
1 - Jack Dempse
4 - Tinfoil Barbs
I was told that the Rainbow Sharks, Bichir and Jack Dempse don't do too well in groups, which is why only one of them at a time. As to the Placo, I don't think I need more than one in a 55g tank. I like the Tiger Barbs the most when it comes to groups. The puffers look really neat, but was told they aren't schooling fish, which is fine with me. I'm willing to throw out some of the barbs to have the puffers.
The store is also willing to do trade-ins if the fish get too large for the tank. They give store credit for wholesale price of the fish... sounds decent to me (better than nothing at least!).
Thoughts?
