Scats are brackish water fish, grow quite large, are ravenously hungry and extremely messy (one of the few fish which make Oscars look clean). They are not suited to FW, Rift Lake water, or co-housing with Cichlids.
Yep, plus they are saltwater fish as adults, so there is no cohabitating. You could do Chromide Cichlids as they are brackish but only when young (scats). Hope this helps!
