My 3 year old doesn't touch the tank or tap on the glass which is nice. She understands fishes die so when we remove them I let her say bye and she gives the fish a military salute before it goes off to Davy jones locker( she lives pirates of the carribean). Then I get the honor of being told I have to buy her new fish. She helps me feed them but she know not to touch the testing kits or the food unless I'm around and I'm proud of her. When she goes to bed she watches my ten gallon until she passes out so that's why I'm getting her her own tank for her new room.
I guess growing up fishing since I was 2 I feel at ease caring about my tanks and I enjoy taking her to the lfs
with me. But she hates cichlids especially red devils since one rushed the glass when she got to close. Almost peed myself laughing. I think natural aquariums are better for infants then those fake cheapies plus who doesnt want to fall asleep to real music such as led
Zeppelin or the smashing pumpkins. I always have porcelina if the vast oceans playing
