Tetra Vacation Tropical Slow Release Fish Feeder Food

Yes, you peel the lid, and remove it from the tinfoil/aluminum bottom as well.

Yes, bettas can eat this food, although they can be pretty picky and may not readily do so. We would recommend 1/4 tablet for 1 week if there is only a betta in the tank.

If your goldfish have not seen 1 of these before, they may be a bit leery of it. We usually recommend breaking a small piece off, crumbling, and dropping it in at the same time you drop the block in to help the fish to understand this is new food for them. Additionally, we do put a certain ingredient in to make it a little less appealing so they do not consume it too quickly.

Yes, 20 days should be okay, but do remove it immediately upon return. Also, make sure the filter is in good shape prior to leaving, and do a partial water change as well. Leaving the tank in great shape is the best thing you can do for your fish.

One more thing I just thought of, check to see if you have any pet sitters in your area who will do a home visit for you. You can contact your local small animal veterinarian or visit www.petsit.com, the site for Pet Sitters International.

Thank you for your interest in this Tetra product! No, we would not recommend feeding such a large block of food to that small of a tank. Our recommendation would be to do a partial water change prior to leaving, and use only 1/4 of the block for the full 10 days.

Thank you for your interest in this Tetra product! Yes, this food is suitable for all of those fish. That being said, the plecos may not eat it, however, as it is not algae based. It is more of an omnivore diet. The tetras and angels will definitely eat it, but you may want someone to stop in every couple of days to feed the plecos.

Thank you for your interest in this Tetra product! Not necessarily; it depends on the fish. We typically recommend breaking a small portion off and crumbling it into the tank as you drop the block down. Considering the size of your tank and number of fish, we would recommend no more than half a block for a week long trip. Take a very small portion of the other half and crumble it as you drop the half block in. They should then follow it down and understand this is a food source. It does not have to be right next to an aerator, that will make no difference.

The shrimp may nibble at it, but the mystery snails need algae, and plant matter such as romaine lettuce or a bit of cucumber rind. They will not nibble on this block. I would recommend perhaps using 1/4 of a block for the shrimp. Snails like some plants, so you might buy a piece of anacharis to leave in the tank for them. The shrimp would munch on that as well.

Depends on the size and type of fish and tank. There is a chart in the lower left hand corner of the back of the package that explains it. For 14 days, 1 block will feed a 10 - 19 gallon tank, so essentially up to 10 small fish.
