Hatch fish, but you MUST have a tight fitting lid, NO gaps.
*Granted in working in my store in 5 years, we have lost 2 hatchs to jumping, and that was over night when no one was around.. We dont keep a lid on it. We have lost more koi, and mollies to jumping then hatchs*
"And 5, very important 5... Don't let me eat pears.. I HATE PEARS."
