My betta fish has started to visit the tank wall regularly. The treats stick well and the fish are always curious. Great for training or just adding variety to feeding.
Ava Gill –
Works well for my community tank. The fish are drawn to the tabs, especially the smaller ones. A little goes a long way and it’s easy to spot in the tank.
Maria Lambert –
I use these as occasional treats. The krill content is noticeable and the fish seem more active after feeding. Very convenient for feeding without opening the tank.
