My 2 year old son LOVES the family fish! He tries too hard to be involved in taking care of the tanks. I let him dump the pellets in for our piranha. I've been teaching him caution, and to keep his hands way above the water. I tell him that she bites (better safe than sorry). He enjoys watching her eat while he's laying in bed. I love being able to share my hobby and my passion with my son. Does anyone else have a little munckin fish keeper?
