I just got a new betta about a week and a half ago. I've been feeding him (Serendipty is his name) Tetra betta food but, since I also have 3 mystery snails in the tank with him, I've also been putting in algae disks every few days or whenever the algae seems low. Today, Serendipity has been eating the algae. Thinking he was just hungry, I offered him some of his regular food and some blood worms, which he picked at but left alone after a moment or so. Does anyone's else betta do this? Again, I haven't had him that long so I'm not sure if he just likes the algae or what.
