I've decided to get the Red Sea Deco Art Nano Filter from Big Al's (not ordered yet) but I was wondering if the Hydor 7.5 w Mini Heater would be a good idea? It's one that can be placed under the substrate, and does not appear to be adjustable. Or if I should just pass on the heater. I may want to put a few male endlers or shrimp in the tank later.
