I was wondering if placing a newly bought platy, who is pregnant, in a 10 gallon by herself would be fine until she gave birth? Right now I have her in a 37 gallon tank with swordtails (1 male, 2 females), a rainbow shark, an albino shark, 4 assorted tetras, and 2 plecos. I want to keep at least some of the fry. I have 2 10 gallons that have nothing in them right now. Planned on using one for the fry of our swordtails. Any suggestions?!?!?
