the set up is important cylinder works the best by far. some people build a kresil tank (probably didn't spell that right) but to complicated and expensive. I tried raising them in a 10 gal rectangle tank a couple times which failed of course and with a 2 gal rectangle several times also which failed. the longest before this last batch I got one to live 16 days I think in the 2gal rectangle. the bigger the tank u try to raise them in the harder cause you have to make so much more food and its already a pain in the butt as it is and harder to clean. plus I hear a cylinder is better cause keeps them from bumping into the sides and has more water movement.When I try ,I did like for a Clownfish breeding in a 10 gal tank,but never past 2 weeks..Keep me post,maybe one day I try again..
