Ok so I am ready to put my Texas cyno cichlid back in the main tank. I have had him in a 20 gallon sick tank for the last 2 months. I did not think he was going to survive what ever sickness he had but he has made a complete recovery. He looks very good and eats well and I want to put him back in his main tank. I am not sure if I should just take him out of the sick and put him right into the main tank or is there something I have to do before he goes back. the water peraminters are the same as far as temp, ph, amon,nitrite,nitrate. I will do a water of both tanks right before i do the switch.
