From what I’m reading it seems like it might involve even more work then SW? Seems like there are frequent water changes...now I’m sure all of this matters on each individual system...and being that most of the tutorials I am watching don’t use a sump this would be why
If your talking the black light glo fish, tetras , danios, ect there just normal fw fish. They are dyed to glow. Its supposed to not wear off and not hurt the fish
