It's just a small 10 gal since it is my first try with a planted tank. I have ferts in there, but sparingly since it's a small tank (and one doesn't want to do an overkill with fertilizers). Surprisingly enough, my clown loaches did better in one of my cichlid tanks while other people seem to have survival problems with them in cichlid tanks! I'll end up sticking to leaving the clown loaches out of my planted tank because I don't want to get more only to have them die (one, waste of money, two, well, that'd be cruel of me!). I have some "vacuums" in there anyway (baby bristlenose, a month or two more and I'll have to move it since anything more than an inch or so in that little tank would be too much!).
