Inquiry (采购产品): Tropical Fish Heater Hi, I am currently developing a product which will require a heater. Let me explain. We will need to keep LIVE tropical fish at a constant 75 degree temperature for a 36 hour period. The fish will be in an air tight plastic container. The container will be inside a styrofoam shipping container. The heating process could be inside the water or something that heats the air inside the styrofoam container. Either way, it will need to be battery powered, stay at 75 degrees and last 36 hours. It also needs to be very cost efficient as they will only be used once and then thrown away. Can you help?
