First off let me be the first to say I had no Idea where to place this so here it is. Second I know they love fine gravel or sand (sand mostly). My one and only question will they eat my Kuhli Loach? I do believe my Bumble Bee Catfish are to big for them. So let me know my dearest friends. Oh and do you like my new Avi its me and it also fish related cause my tank is in the background!
