Hi everyone, long time no see as usual. I hope everyone had a nice winter break and a happy new year.
I'm interested in putting one of the nerite snails in my mom's fishtank into mine. There used to be a bad algae problem so a friend gave us two of hers, but now they keep the tank spotless and I'm worried about them getting enough to eat. It has either mosquito fish or wild type guppies in it. We've had them for about 8 years now so at this point they're probably genetically different anyway. The point is that these fish do not eat their offspring, and so the tank is always quite crowded. That combined with overfeeding and less frequent cleanings and my much higher standard of hygiene in my tank lead me to be a little suspicious of what might be in the tank.
The fish are all frightening healthy and have left the snails alone for the most part. They were taken out of the friend's tank a few months ago and nothing out of the ordinary has occurred since being in this tank so I'm not worried about anything coming with them from her tank or the pet store.
Is there anything her tank could pass on besides poor water quality and is it possible to quarantine snails effectively?
