I gave all of my Africans away in preparations for my new FH (5" Golden Pearl Dragon). BTW, he is on his way to my house as we speak. Anyway, there was a 5-6" synondontis in that tank. Should I leave him with the FH? Or can I put a pleco in there? if so...what size should the bottom fella be. I guess what I am asking is what should I put in there to work the bottom? Or leave it alone?
