55 gal aggressive

[deny]

My peacefull 55 gal FO tank now has no fish. The only residents are now a coral banded shrimp, and a few snails and hermits. I was thinking of switching to an aggressive tank. Can I do that in a 55 gal FO tank??? What is recommended to start with for a beginner??

Lol, i just switched from aggressive to peaceful.
Anyway, the best fish to get that is practically unkillable are eels (my personal belief.
I had a Snowflake eels and a fimbriated eel. They are very hardy.
They will eat your remaining inverts though. If you were going to take them out, i would say get an eel lol
Dont get a fimbriated eel though, they are mean and nasty towards other fish!
Good luck
