Well, Ive had some bad luck when bringing home some fish in the past and I didnt want to bring home some disease from the store. I recently purchased some dwarf pufferfish for my puffer tank and they had ICH, not fun with scaleless fish. 2 out of the 3 died.
The last time I bought some guppys the chick at petsmart used some water from a different tank and they brought ICH to my 20 gallon. If I had been more experienced then (a few months ago) I would have told her to forget it. I had a few fish die from that ICH incident.
So for cheap guppys I want to make sure they are healthy before putting them in my community tank. They pregancy/labor is secondary.
Only 1 fry died so far.
