So I bought a 5" Common Pleco and this is my only Pleco. So basically I don’t know if he’s eating or not. At about 7 or 8PM I turn the lights out and have tried several foods. First is Hikari Wafers, I don’t think he ever eats these and I think it’s more of a game to see which Cichlid can break it up. I’ve tried unblanched Squash, I tried blanched squash which when I woke up one morning and came in he sucked on it for about 2 seconds then went to the glass. I’ve tried honeydew melon and Cantaloupe all with a ScrewCumber but in the morning they all look the same. I’ve also bought but have not tried a yellow squash and a yam. So is there a way to tell if he’s eating and for the yam should I blanch it or not? Thanks in advance!!
