I've never kept polys or ropefish but seeing the pics here has me thinking about getting 1 Senegal and 1 ropefish for my 125g tank once i get it set back up. I was thinking about adding an African Brown knife and wanted a school of something but didn't want Congo tetras because i've had them many times in the past. I was wondering if a group of 7 or 8 Madagascar rainbow fish would work or would they end up as snacks? (I know they aren't actually African but figured it was close enough) I was also wondering if the rainbows were a bad idea if a Paratilapia polleni might work. Or, would it be best to get maybe 2 bichir and 2 ropefish and be done with it?
