fairly easy, once acclimated theyre pretty hardy fish. things to keep in mind are that they can be shy and dont like bright lights, you will notice they stay in the shade most of the time. they also MUST be keep in groups, ideally at least six, but no less then four will be fine. ive got five in my 30 long along with a few botia kubotai, a molly, and a pleco. the kubotai, glass cats, and molly recognize me and come out from hiding when i sit near the tank i love my glass cats, they hover so elegantly
