(okay, so i accidentally closed my browser, so i have to type all this again. -_____-)
most people recommend 2-4 pellets a day. some feed only 2; possibly 1 in the AM and 1 in the PM, or 2 at once. others feed 4 a day, usually 2 in the AM and 2 in the PM.
i personally feed 4 a day; lately, i've been doing 1 in the morning, 2 in the afternoon, and 1 in the evening, but i plan to change it to 2 in the morning and 2 in the evening, to prevent bloating.
i recommend feeding some frozen
bloodworms or frozen brine shrimp, along with pellets, for added protein. i feed my boy bloodworms 3-4 days a week. when i do, i give him 1 pellet in the morning, and 2 bloodworms in the afternoon. it's best to use tweezers (i'm actually temporarily using a chopstick) to handle the bloodworms.
you can also feed them freeze-dried
bloodworms or freeze-dried brine shrimp, but since they're not as nutritious, they should be used as a treat, once or twice a week.
it's also recommended to fast them one day a week to prevent bloating.
i'm sorry if this is too much. haha i hope this helps! (:
OH, and for the heater, i've heard great things about this one:
i've bought two different heaters from petsmart, and the first didn't work at all, and second overheated my tank. i plan to buy the one above eventually, probably in the fall, since i don't need it at the moment. (my tank is a constant 78-80*.)
