When I was a kid my dad enjoyed fish and we had two freshwater aquariums and one marine aquarium. In the marine we had clowns, starfish, a few other fish and a very large saltwater hermit crab. Surprisingly the hermit crab ended up eating everything except the starfish.
I then went a LONG time without any fish but always loved visiting aquariums and looking at fish. About a year ago I was dealing with bad depression so my boyfriend got me a small tank, some live aquatic plants and a betta in hopes that having a new hobby would help. It certainly did and now he's afraid of me becoming a crazy fishlady. Right now I'm really into south and Central American cichlids. I think it would be nice to one day have another marine tank though.
