Re: stunted growth

["Cory and Susanne Williamson" <webwill@infinet.net>]

I have three 5 gal tanks with 1-cm long fry in them and they still seem to
be growing well- I do up to 30-50% water changes every second day.  The fry
are about a two and a half months old now- If you have the space and don't
have time for tons of water changes- then I would go for a bigger tank (or
reduced #'s of fry)- I have sucessfully raised over a hundred bettas in a 25
gallon tank, but the daily water changes just about drove me nuts- Basically
what I am trying to say is that there are no hard and fast rules for fish
densities other that they need to have a constant supply of clean water- so
as the fish biomass goes up, either water changes must increase in volume
and frequency or the water volume must get larger. Of course you can
complicate the system by adding elements that will used up the fish wastes
(ex plants to use up nitrate or carbon to use up other organic wastes etc.)

Hope this helps.
