I know snails produce waste so there must be a bio-load. But how much? I have a 14g with some molly fry in there. I had unwanted snails in my 20g so I figured instead of killing them I would just put them in my temporary 14g fry tank. So after putting a few in there every week and a few weeks later I now have about 200 snails because the multiply so dang fast. I really don't mind the snails taking over because the tank is setup for my fry to grow and then I would maybe get rid of them.

What I wanted to know is are they putting too much stress on the water and fry in there with their bio-load? I have a filter going and do weekly water changes. The fry seem to be doing great and growing quickly. So I can't tell if there is anything about to go crazy with so many snails in there or if it's fine.

These are the snails that are about the size of a pea. They are laying the egg sacks that look like clear jelly with 15-30 eggs in there. They lay them on the glass, plants, decorations, etc. Again, if having so many won't cause any harm for a few weeks then I don't really care that they are there. After the fry are gone I will probably just collect the snails and throw them in my father-in-law's outdoor goldfish pond. He could use the snail help anyway.

Thanks.
 
You'll need your test kits to tell you if your water quality is fine. It just depends mostly how much foods you allow that also influences the number of snails and bioload.
