Thank you for all your advice! It's all good, I don't mind sharing! :)
Yes, Neil is actually in a large critter keeper, which I believe is anywhere from 2.5-3 gallons, and I got him a Hydor 7.5 Watt Slim heater, and for my other two (the girl, Chappy, who's in a 1.5, and Ray Charles, who in a medium sized critter keeper, that I believe is 1.5-2 gal.) I got them a different kind of heater, the Deep Blue Bettastik 7.5 Watt Mini Submersible heater.
