Yeah but this isn't a air-free design. It tells you to feed them with a toothpick (which is handely provided
) thru the top.
It also gives instructions on how to clean the tank once it gets "cloudy".
I don't know how a subrate could eliminate enough ammonia and/or Nitrite build up to keep it from killing your fish. Even in a big tank with 3 small fish...eventually it's gonna build up and kill them if the water isn't changed.
This isn't a "bio-dome" or an "experiment" this is simply a lazy person's excuse of a pet. They are marketing this towards the parents of small children and/or people who work in offices...so that they think they are getting a maintence free pet. Which just isn't true. Fish are messy, plain and simple. They aren't easy keepers, as they have numerous things that need to be checked and done often to keep them alive happy, and healthy.
I wrote them that e-mail..I'm not, however, holding my breathe waiting on a reply.
If people want a maintence free pet..they should buy a ant farm or a packet of sea monkey's (not brine shrimp..the crystal ones you buy at wal-mart) or a robot dog, imo.
I have 2 dogs, 9 individual fish, a community tank, 7 cats, and a family of raccons (they eat off the back porch), 1 8 yr old, and a full-time job....if I can find time to clean up after, feed, water, play with, and maintain all of that....there is no way any one person who wants/has a fish as a pet can tell me they don't have time to change a cup full of water (not that I think they shoudl be in a cup full of water mind you) for 3 fish everyday. It's just plain laziness, and it urks me to no end.
