IceCap Fish Trap (200 Medium) https://a.co/ine04MtAnother option is this fish trap from Amazon. We just took the rocks out so I haven’t tested this yet, but am using it as a mini hospital tank within our hospital tank because one chroma was being picked on lol. But it seems like it would do the trick of catching fish well. Another option for chromas is catch ‘em during the night. I caught all of our chromas at night.
Only thing that sucks about it is it has these dumb protective stickers that are kind of a nighthmare to remove lol. Took like 20-30 minutes lol
