funny story, today I got home from the gym and i see this black thing on the floor next to my tank and i thought great, a fish jumped out. I thought it was dead but it moved when i picked it up. So the kilifish i bought from you manage to jump about a foot from my tank even though i have a cover on it. Theres a lil bit of space but i dont see how its possible that it can jump or even fit through the cover. All the fish and shrimps, plants are doing fine btw.
