the tank is a 65l, and he was about 2" - 3" in size so only small! It lives with 4 angel fish, 2 south african butterfly fish, a 7.5" ornate bircher and a plec.
Was in the lfs with all the other freshwater fish and not the brackish/marine fish as i would have steered clear. Looked perfectly happy and very active in the shop and the same in my tank last night, ate bloodworm and catfish pellets last night as was very active.
This morning hewas not looking good, stuck in my plant facing up, still breathing but lifeless!

Still thesame now! Quite upset as he is a loverly looking fish and hate it when they die due to my possile error!
