ATM too many, bought a job lot of 25 juvie blue cobalts, keeping the best 4 and giving the rest away to friends, have added the pigeons and leopard since as I want to grow them on for breeding stock. Will finish up with 8-10 adults but parameters are fine right now so in no hurry to move on the surplus stock. The plants are starting to take over so thinning them out at the weekend, have never run CO2 as I don't want to jeapordise the fish
