Are Tigrinus cats known to be jumpers? I have glass tops on my 180 with a canopy over that. Maybe I should fab up some locking plexi lids? I would just die if the Tig ended up between the glass tops and the inside of the canopy!! I also would like to know if anyone here has or has had a Mystus Wyckii (aka-Hemibargys Wyckii, Black Devil Cat, Crystal Eyed cat, etc)????
