Carrot and Gareth

LOL. And no! Those are not their names. I have yet to *want* to name them >_<
Last week, my nephew had "catching fish" as part of their activity in preschool. He ended up with these two and since no one wants to rear them, I decided to just take them. I don't know how long they will last. Coz I'm not really a fish person :D

Since it was a sudden decision to keep them, I didn't have any fish food for them. So I fed them with cracker crumbs for the past few days *LOL* Yup, those that I take for breakfast with my cup of hot Milo :P Well, they apparently don't seem to mind. These are not really the oily or buttery kind, so the water is still clear. I gotta remember to go get some fish food after work today >_<
Anyone with advices as to how to rear these?
