I am going to try and feed my bristlenose plecos lots of diferent fruits veg and see if they like them however i will give a rating on each one with a 1 being barely touched it and a 10 eating it before it hits the gravel.
Zuccini/courgette (10) My BN's are waiting for it by the time it hits the bottom.
Cucumber  Another house favorite but not as eager as zuccini.
De-Shelled Peas (3) For some strange reason my BN's dont like them.
Algae Wafer (9) they will latch on and wont let go, not to a P.Gourami or anyone.
Carrot (5) Small munch not really that interested.
Apple(1) It has made my water cloudy never again
Feel free to tell me any more
