hey, i heard that you are going to collect some minnows for your fish tank, and i just had a question. I currently have a 5 gal with a platy and a wild baby yellow bullhead. I am going to release the bull head next year, but i'm getting a 15 gallon soon. Do you think it would be a good idea to keep some Brook silversides in there. They only get about three inches long, so how many do you think i should keep? Thanks for your time!!!
