I'm looking for ideas for tankmates for my phenochilus. I was thinking rostratus but want to get some other opinions. I currently have 11 phenos form 2-3.5" . I plan on thinning out a few males when they become more apparent. The tank is a 5' 100 gal tank. I'm running 2 aqua clear 70's and 2 hydro5 sponges for filtration.
