Hi I'm new to this forum and and just thought I would talk about my tanks. I have 2 rams, 1 angel, 3 kuhlis, 2 platys and 6 guppies in my 30 gallon. In my 55 gallon I have a baby tiger Oscar who is 2 inches right now and is happy as ever and eating well. Hoping to get another someday. Well those are my tanks.
Sounds like you avoided stuffing your 55 with Oscar. If you plan to get another Oscar you may want to do so PDQ. Once the current one claims his / her turf trespassers will get the death penalty. A 55 is actually kind of small for two full grown Oscars, maybe even cramped for one really big one depending on who you ask.
