this might be a bit of a silly question, but as someone who likes to make care sheets for reptiles and such, i'm curious.
are there any pets that REQUIRE bioactive setups? as in, no questions asked, it definitely should have one?
i know pretty much all animals that can be kept in bioactives will benefit from them, but i'd like to know if there are any animals that pretty much have to live in one if you wish to keep them in captivity.
this question could also probably apply to fish (as in FOWLR/reef/planted tanks) as well as other reptiles besides geckos, hence why i'm posting it in the off-topic section of the forum.
