Tetra Weekend and Vacation Feeder Slow-Release Fish Food for Tropical Fish 1.06 Ounce (Pack of 1)

These work good. Used 1 for over the long weekend. My fish took right to it easily, so I was able to go away without worrying about them starving.Follow the directions, I put a whole tab in, but really should have only put a half of one.Good value for the cost. Definitely buy again!

It works as it says

0 STARS!! This feeder seemed to have good reviews and we tried it for a 5 day trip for our beta fish. When we returned the tank was brown, slimy, and the feeder had not disintegrated at all. The fish was healthy and vibrant when we left, but had clearly passed several days before our return. RIP Macaroon

and it doesn't mess up the tank! But my Bettas don't seem to like it much. When I put it in I break in a few pieces, the bits that fall off they grab right away but when I return the Betta sorority tank still has almost all the feeding block and the guppy/snail/shrimp tank has no trace of food. I have used for up to 8 days and so far have lost no fish and none seem starved when I return. I will continue to use.

We travel often and I am sure to keep these on hand. We have Angel Fish, African Dwarf Frogs, Pleco's and a few other community fish. One of these disks lasts about 5 days in my tank. If we plan on being gone longer, we are sure to leave 2 disks in the tank. We have been gone for 11 days before, leaving 2 disks in a 55 gallon tank, and have come home to chunks of the disk's left in the bottom of the tank. Simply scoop out what's left over and toss out, then continue feedings as usual. This food is compressed in a tank safe gel and slowly dissolves, giving your fish the nutrients they need. If you have bottom feeders, they are quick to find the disks and work the food out themselves, helping the process. From my experience, this does NOT make the disks dissolve any faster so no need to add more with bottom feeders. Be sure to remove the disk entirely from the package. Don't leave it in the plastic cup after removing the lid. REMOVE IT FROM THE CUP ENTIRELY and drop the disk in the tank as far from the filter as possible.

The fish seemed to like it well enough - after I had to take the food out of the metal feeder. They apparently couldn't get it out of the container. I double checked to see if there was some film I needed to peel off the top of the feeder, but couldn't find one. They barely got any food out of it until I dug the food out of the container and just plopped it into the water without the container.

Works great and doesn't leave big mess behind. I have used it so far for two vacations and they have worked great!
