Alright I'm super interested in pipefish. I want to make the jump and get a pair of blue stripes (not rushing just stating my ultimate goal). I haven't quite decided on a tank. I have a 12 gallon nanocube but still debating if that is adequate. So bare with me. The tank Will be set-up refugium style so I can get the pod growth I want. My biggest problem is the 12 gallon has a metal halide, I want to keep the tank around 74 I don't think I can do it with my current set-up. How do you guys keep your tanks cooler? Do you run a chiller? This is my one big hurdle haha. Please give me your opinions or experience.
