Apparently that is meant for the full grown size of 14cm, mine is a mere 2cm lol. So i asked my LFS and they said its fine, they keep them in an even smaller tank... so iam at a lost, I dont have a tank that is that big, a pond is on its way in a years time tho, I guess it can go there once its built. Lepornidus is just fine as it seems cuz the full grown they refer to is 40cm mine is only 3cm, so that can go in the pond once its over grown too. Anyways thanks help, its eating shirmp meal suddenly, also i realised it started to eat the algae i grew for him on the rocks, its little but enough i hope...
