Its me again!
Ive been feeding my fish (mainly my stingray, silver aros and catfish) frozen smelts that i cut in pieces no more than 1cm wide... They eat it... But not with the voracity i would want them to... This week i started mixing some tilapia fillet and they seem to like it a lot more than smelts... Im considering switching to tilapia as a base food... But im afraid that it will have too much fat... Am i wrong? If i am... What would be better? Only the fillet or the whole tilapia (bones, skin and all) just gutted and cut in pieces small enough for them to eat?
