I have a pregnant Mickey Mouse Platy. I'm getting a 2nd aquarium so I can keep the babies separate in hopes that the other fish won't eat them. I've been told by one website to not use a filter in the "babies" aquarium. Then another told me I needed to. One said to get a fish net to separate them, another said it would stress the mom out. One said to keep the water at 65-72 degrees, one said at 80. The only heaters I can buy around here cannot be changed, they are automatically set for approx 70. I'm very new to the whole fish-business, only had an aquarium about 2/3 months, and the pregnancy was a bit of a shock, both happy and "ACK!!!", but I'd like to make this fun for my kids so am trying my best to do things right. Can I get some info from some of you that are more experienced? Thanks.
