Hello! Right now I have a low-tech20 long with 2 huge and growing pearl weed bushes in the back corners and trying to establish dwarf chain swords in the front. and yes, I see the algae. but that has nothing to do with my question. If I added a trio of rocket killifish would they spawn and should I expect fry? Will the otos eat the fry of the rocket killi or would the killi make a quick snack of the oto eggs? what other nano fish will breed well with otos in a heavily planted tank?
