HI Discus experts I got my 2 discus 7 days ago and they are in a 10gal quarintine tank. They are looking healthy,eating properly. When is it safe to add them to my 75gal? I ask because I am planning on getting another 2 soon so will need to put the new ones in the 10gal... Atm I am doing 25% twice daily wc. Is that too much, little.etc? And I feed them 4 times a day with frozen bloodworms, flakes, pellets and ox heart.
