so i have a pair of convicts, one pink and one standard. less than a week after they were in the tank they laid eggs and ushered about 40 fry into the world. i want to get rid of the pair so that i can change the tank into a different setup that doesnt include convicts. i will eventually sell the fry as well but i want to prevent more breeding and would also like to allow for a cleaning crew to be put in (otto's, plecos and shrimp), something i think the fry would be ok with but the parents simply wont allow. how big should the fry be before they can do without parental guidance?
