nice Prochilolus you picked up there! my only advice to you is keep your water clean be careful when approaching the fish tank, the prochilodus will startled and get scared and often they will either hop out of the tank or swim insanely fast where they bump their head and nose into the heater or object in the tank which led into cuts and scarring around the nose and the head. Some of my Flagtail have cuts and scar on their nose but i use stress coat and it heal pretty fast but if you get unlucky the injury on the nose is permanent. SO BE VERY CAREFUL When approahcing the fish tank
