Like I said many "commons" are omnivores (see planetcatfish) & need both veggies & proteins & that it can depend on species. Very few fish survive on veggies only. Auf wuchs may look like algae is actually a biofilm of micro-critters & some algae. That's why I like Repashy.
If you'd read my post I did ask if there was real wood in the OP's tank. & not all plecos need it but they may like it for the stuff on it not just the lignins. As for fiber, peas & sweet potato have more than, say, cukes, it also depends on what part of the veg the fish eats.
Hikari foods aren't bad but their algae wafers are similar to their other wafers. Other brands have much more spirulina & other veggies, some even have wood.
