wwestar the loaches are khuli loaches which grow 4 inches maximum, you are probably thinking of clown loaches which can potentially reach 18 inches or more, khulis are really the only loach recommended for tanks less than 20 gallons.

Yeah i didn't explain why i said that. I posted a thing about my loach. "orange finned loach" Who i bought at WM months ago. At WM it said max size 4 inches and the boox i have it says max size 4 inches. But then when i posted about him people here somehow are finding info that says they grow 20 inches or something crazy like that. And im not fimiliar with loaches and actaully now dispise them.
Thats the only reason i said that. I have no hell of a clue how much a khuli loach grows.
This is not a dig wwestar, just a word to help the newcomers.
If you have no idea as to the information please dont post it as factual.
If you have a opinion please state that its only your opinion so beginners are not left even more confused.
