Thanks Badflash for the information. Now I' m going to have to practice. I hope you guys are patient with a newbee.
The fish are Tilapia Blues. I have lots and lots of them. About 1400. And yes they will outgrow that tank. I'm thinking of getting a collapsable kiddie pool for them and their cousins - the 500 bunch born 10 days later. At least till I can get them outside in the Spring.
