Yea I dont think i will take him out of the tank, so he probally isnt a true [100%] rhom. i just want him to grow over 10 inches in my big tank. thanks for all the replys on my P.

i could be wrong, but i don't see that happening if it is only 6 inches long now after owning it for 5 years, that's if it even is a rhom. if it is a sanchezi, which i think it is, then your fish is full grown.

i agree, and if it's a compressus as some have suggested it will max out at 8-10",
