Living in HI do I need a heater?
Just wanted to know if people here in Hawaii use a heater for tropical tanks or not. I don't, and during the summer I noticed that my tank's temp was running at about 79-80 degrees, but currently it's closer to 75 on average. After noticing this recently I'm definitely thinking of getting heaters for my tropicals so the temp is more stable. Plus I know my higher temp fish would appreciate this (bettas, GBR, etc). Any thoughts?
