We are amateur neon tetra owners. Our main worry since we have had these fish had been how do we take care of them when we are away. You can get 1 week food tablets which can slowly feed your fish over a week. But if you plan to be gone longer than that, what do you do?
It turns out you can just buy a nice and cheap $20 automatic feeder. It can hold 6 weeks of food and can be programmed to feed upto 4 times a day. It also has a setting that during each feeding time it drops food twice � with an interval of a minute between them � to help the slow eaters have a better chance at getting their food.
We tried it out yesterday and it works flawlessly. Now only of we could find another cheap way to automatically change the water once a week without doing any special hardware setup
Here’s a Petco link though it’s much cheaper on eBay. http://www.petco.com/product/105443/EHEIM-Automatic-Feeding-Unit.aspx
