She's about 1". Yes, I just approached the tank with a tape measurer-you know how I am with my babies

. I'll add some extra plants and maybe some smaller "african proof" ornaments and then do as you advise. That'll give the "boys" a chance to regain their finnage (it's very minor-it just happened in the last 24 hours) and then I'll add one of them to the african tank as well.
There's 13 africans in there-one of the "miscellaneous"-I think he's a rust cichlid got attacked and I lost one of the Petco electric blue johanni's-he never did act right. My guess it's borderline stocked for an african tank. Does that sound about right?
Now the other option would be the princess's african tank-but her blue (I think socolofi or afra) are pretty aggressive creatures.
