I have a mudskipper in a 15 gallons paludarium. I feed 1 cube a day but I don't have enough room for a UAS. I was thinking to do a hang on glass waterfall scrubber, so I need a 4x6 screen and I would go for 4 660nm and 1 455 nm, for the pump I need 140 gph. Never seen anything like this, do you see something wrong with it?
