I have a 56 gallon setup. I am running a filstar XP2 for filtration. The PH is 6.4 no ammonia no nitrates or nitrites and 86 degrees farenheit. There is a variety of driftwood (makes the water brown) and Some live swords and other live plants. I have a royal Blue Cobalt discus, A Golden discus, A red pigeon blood, A gold ram, a blue ram and a fiddler crab. When its feeding time the Royal blue comes out but most of the time they are almost unable to be seen. They dont swim around much. Should I put more fish in? Are they lonely. There is not much traffic around the tank and they dont seem stressed. I know discus can be moody, but how can I make them more active. In all honesty they are pretty fish but probably the most boring i have ever kept. Any ideas? Also how do I do a planted bottom ie: LIke a lawn? Thanks everyone!!
