Is 72 degrees too cold for this tank? I moved the heater to the 40gallon with the cons and now when i put my arm in this tank, it feels very cold. The thermometer reads 72/74.
Got another API Freshwater Test Kit in the mail. I only ordered one but Petco sent me two, one of them several days after the other. All my tanks are good except this one. It's nitrates are high which is odd to me since it's the most heavily planted. Would a 60% water change hurt?
The larger of the two gouramis nips at the smaller one from time to time but he isn't causing damage...just annoying him. Is this normal behavior or is it time to move him now?
