I have a 12 inch sailfin pleco that I've had for 3 years. He (or she...) loves veggies. Our garden is producing a lot right now so he's been getting squash etc every night for dinner. How much is too much? I don't want to overfeed him but I don't want to starve him either. Right now he's been eating a small (4-6 inch) whole zucchini or yellow squash every night. Is that too much? Should I feed him less? The seeds are making a mess in the tank but I figure its worth it if it keeps him healthy and happy.
