was he jumping for a reason?did you startle him or anything like that. aros jump naturally and of course in the wild they dony have invisible barriers(glass)when i was a teenager i had 3 aros jump out of covered tanks. one broke the glass lid on my 125,so ive learned to make their habitat more natural with floating plants and places they can hide(very shy)no more accidents.now i have 3 healthy aros 32"-18"-12" all doing well.imo if he eats and swims around ok then he will be fine. gl and nice looking fish.
