any body elses' clown knife like to surface even jump my ck comes about 6" out of the water a couple times a day its pretty funny to watch i think that hes just a weirdo
i used to have glass covers that were like an inch above the water but he started getting marks on him from hitting the glass so i now boxed in the top so he has room to jump my aros love this to and its interesting seeing my eel try and climb up dry glass
mine does this a couple times a day, placed some meshing around the top of the tank so he doesnt injure himself on the cover i had on there before, but when he jumps he JUMPS, really fun to watch when i catch him in the act
