ill soon have my 50 gallon tank freed up (36x18x18) and was thinking of throwing together a litlle group of CA's. possibly some cryptoheros species and a meeki or different variation of thorichthys with a nice sandy bottom for them to sift. i would love some suggestions because i have a lot to learn in terms of keeping these genuses and would love a bit of guidance as to what they might need. feel free to post some photos if you get specific with a species id love to see em. thanks
