I am currently redesigning my tank layout as I have got a little bit bored of it. So whilest having a little move around, I accidently scared 1 of the Denison Barbs and instead of swimming to the other end of the tank it jumped out of the tank (20cm in the air, which was quite impressive I got to admit), over the edge of the tank and landed on the cabinet. Luckily I managed to get it in the net and with a wet hand over the top of the net I got it back in the tank. Overall the denison must of been out of the water for roughly 10-15 seconds. I can't see any damage to the fish, there aren't any damaged scales and he seems to be swimming ok, but was just wondering is there anything else I should look out for if it happens again (hoping it doesn't). Thanks.
