Im also having the same problem with my aro. He is now about 8-9'', Ive had him from the sac. When I walk up slowly to the tank he goes crazy bouncing off the glass. My water parameters are fine and I do weekly water changes about 35%. Hes is fine when the lights come on and off, just when I walk up to the tank he goes nuts. He was in the tank alone, but yesterday I added a jag hoping a tankmate might calm him down.
