How do you feed monster fish while on vacation? I have used a house-sitter in the past, but I had trouble with over feeding fish & underwatering houseplants. The autofeeders I have looked at clip on the tank, but if you have a big tank they don't fit and if you have big fish or a lot of them the food reservoir is too small. My fish actually laugh when I put those longlasting feeding pyramids in the tank. I usually just feed a little heavy before I leave and then feed a little more often for a couple days when I get back. That works for a 4 day weekend, but what about a 10-14 day vacation? It would be nice to solve this problem without spending a gazillion bucks.
