how you guys make the pieces of cucumber to sink down to the bottom of the tank for your pleco? Sometime I have to crush the cucumber or use steel wire to make it sink down and that is kinda annoying!
You can try sweet potato for the plecos instead. Most of the time the fresh sweet potato will sink without weights. The older ones tend to float because it may have been dehydrated somewhat. My plecos still comes up to the top to eat either way. Regular potatoes alway sink not matter old or new. Good Luck.
