OK, so I decided to go with a pair of severums (one turquoise/green and one gold) in my restocked 55 gallon. Both are juvies right now. I also have three tiger barbs in there (from my previous tank). Do you guys think there is room in there for a smaller species of pleco that won't outgrow the tank and also maybe a small group of giant danios? I'm just looking for ways to fill out the tank with some non-cichlid species. Thanks.
