Hello. After a bit of a break I’m converting my 8’x30”x24”, 300 gallon from a planted tank to a hardscaped cichlid tank. I’ve been growing out geo sveni and red back scalare for about a year with plans to eventually put them in the tank. I have about a dozen of each. Recently I was able to get a trio of very small crassi. I’d really like to use them as well. I know they stay smaller than regular oscars. Do you think this would work?
