well i just counted 15 fry in the 5.5 and there could be more in the hornwort plant so i just have a rough idea on how many there are lol but anyway ok my 20 gallon long will be open this spring and i will be able to breed stuff in it ok my question is do i want to breed crowntail bettas,bristlenose plecos, or convicts in it? i would like to have something profitable in it that i could sell to the lfs or craigslist or somthing so what do you guys think?
