I am wanting to go with fish with a little color or just nice to look at. I'm eventually going to get some neon plastic plants and some real plants I'm just not sure what are inexpensive and easy to care for. I was wanting a Black Ghost Knife but they are Semi-aggressive and I'm not sure I can put one in with my tetras, Danio, and glowfish. I also think that those (tetras and others) are a little to small for my 55. I need another tank then once some of my convict cichlids (I have over 50) pair up, I can get rid of most of them and move them to a smaller tank and move my tetras to the tank the cichlids are currently in and free up my 55 for bigger fish. Idk, this is new to me
