I kept five adult Discus
that I raised from size of fifty cent piece in a 80 gallon tank for nearly two years. I would recommend that adult fish be purchased for little fish(Discus
) ,,need several small feedings a day to achieve growth potential and to prevent stunting. These frequent feedings also mean frequent water changes to maintain water quality.. Adult Discus
don't require the same amount of protein that small Discus
do and twice daily feedings and weekly water change would suffice IMHO. Young Discus
as mentioned will need several (three or four0 feedings each day and in my expierience,,benefit from two to three water changes a week. Some who care for these young fish change large amounts of water on daily basis but mine seemed to fair well with three feedings each day and three weekly 25 to 30 percent water changes.Opinions Vary.
The only cory species that I am aware of that would appreciate the 82 to 84 degree water that nearly all keepers of this fish keep them in ,is the Sterbai cory. Water is too warm for longterm health and happiness of other corys. I kept mine with sterbai corys,and German blue and gold rams though all but one of the rams died due to moderately hard water that I attempted to keep them in. Discus
Faired well and grew quickly in moderately hard water with pH of 7.4 but they were tank raised specimens that had been acclimated to the harder water.
Fish can be skittish but once they become comfortable in new enviornment and the enviornment is maintained to preserve water that suits them, they are indeed a lovely fish and not too dificult. They do not tolerate poor or deteriorating water conditions well. Hope some of this helps.
