Fish for 3 year old boy

guppies,white clouds,white minnows,betta, shrimp and snails have been suggested. just remember you cannot have very many of any that you choose. Cycle the tank before you add anything but a betta.

there are articles on how to do a fishless cycle here somewhere
 
I would definitly suggest a male betta with a dwarf frog or a snail or even a couple ghost shrimp definitly need a heater if you get something to go with a betta like the shrimp or frogs. but dont go to walmart to buy a betta they dont take care of their fish. DONT GET A GOLDFISH!!
ARRG I HATE GOLDFISH!
 
Just to chime in with everyone else, I recently bought a five gallon tank for my 2 yr old's room. It's cycling right now (thanks bio-spira) but it will be populated by one male betta, nothing else. Also, I'm heating the tank, using the unregulated mini-heater you can buy at wal-mart. Keeps the tank about 76F. I live in Ohio and the house gets down in the mid-60's during the day, way too cold for a Betta.

If you're wondering about whether to buy a heater or not, you can do the calculations that involve the volume of water, the specific heat of water (1), the length of time of the tempature and the relative air temp to see how cold the water will get, or you can just spend the $10 and get the heater... :)
 
"if you do get a betta, 2 small corys" said Emg.

I totally agree!!! I have a 2.5g and a male betta and 2 dwarf spotted corys and they are so happy there. I had an underground filter and don't recommend it for such a small tank. I got an in tank filter from Petco that fits perfect in the small tank suction cupped to the back of the tank.

The betta gets the few flakes (which he only needs per day so he won't get fat, mine will eat everytime I feed him if I let him!!) and the corys clean up the food from the bottom and keep it real clean!!!!

My 3yr old when we got the fish, now to be 4 in May, just loves our fish. He calls them his fishy friends!! (We also have a 20g with 13 fish in it, he doesn't have and couldn't keep up anyway, with names for all of them.) When we leave the house he says goodbye to the Betta named Jr. and the corys named salt and pepper, and he says to the others "Goodbye fishy friends" How cute!!

It has also began to teach him a bit about life and passing. (We had the goldfish in the bowl and I don't have to tell you how that turned out)

Good luck with and most of all patience and have fun!!
