These are popular with every fish and critter. I have mollies and Limias, usually surface feeders, who dive down to the substrate to munch on these. The plecos, SAEs, nerites, random snails, and Amano shrimp love them. And the Neocaridina shrimp swarm these pellets.
Snails and plecos LOVE these!
Plecos and other bottom feeders love it.
