Ive always loved aros, my buddies got a 2' one and always watching him as made me want one. So i ended up getting 1 about 3 days ago. hes Only with a mosaic gar, the lfs told me they might have problems. But i have seen any yet. I got home today and the aros fin where it meets at the end of the body looks all beat up. like theres a couple missing. It doesnt seem to be the gar becuz ive been watching them for 2 hours now and they both seem to be fine. The aro is still acting like he has been. VERY active, happy, i just dont know wut could have happen. My only thought is he swam by the power head and it sucked him in a lil. Should i get rid of the power head? will the grow back?
