So, I just bought 4 baby bristlenose plecos a few days ago. 3 of them were the regular black color and one albino. In the tank they were in they were eating zucchini. Since I have had them in my tank I have attempted zucchini every other day. I have never seen them eating any of it but from the ones I can see they don't appear to have sunken bellies. Every so often I see them on the driftwood but most of the time they are on the glass which has no visible algae. So what do you think? Are they getting enough food from some possible algae that I cant see, are they getting enough food from the driftwood or are they slowly starving? I try to see them eating at day and night but even at night I don't see it.
