I brought home a tank around two months ago and I've been planning to add some new fish and plants. It is a 55 gallon tank with one filter, a heater set to 76 degrees Fahrenheit, two tank lights with covers, and an automatic fish feeder. The inhabitants are: two male sword tails, two angelfish, one black moor goldfish, one sailfin molly, two two pea puffers, two fancy guppies, one large chinese algea eater, a black khuli loach, a neon blue gourami, one bamboo shrimp and two cory cats. The acessories are: one pumice stone with a hole inside, two pieces of driftwood, some christmas moss, a bamboo plant, an amazon sword plant, a north american water primrose and an elodea. The substrate is medium pebbles, I may add some sand. I feed them tropical fish flakes and bloodworms. The bloodworms are fed twice a week and the flakes are fed a quarter teaspoon twice a day. The readings are: ph=7.4, alklinity=100ppm, hardness=120ppm, Nirtite=0ppm, Nitrate=10ppm. Any recommendations?
