Thats what i thought at first but nothing in the tank seems to be chasin it, i thought two blue botias may be the culprits at first, specially sein as they have the spikes below there eyes but they seem to be just chasin the clownloach nothing else, im still baffled, im presuming if he was stressed he'd develop more than just a colour change but would still like to no whats happenin to him !
