So i decided i think my little 2'' pleco i have to keep my tank algae free might not be getting enough to eat. I have read that they like to eat vegetables such as zucchini and cucumbers. I plan to get him some of that, but my question is is it bad to just leave some sitting at the bottom? I know it's not good to leave other food that isnt eaten such as worms and what not due to the breakdown of organic material, but will cucumber and zucchini be harmful to the water if left sitting in there for a couple days? I Plan to stick some on a paperclip and just stick it into the rocks at the bottom and let it sit till he eats it all, but please let me know if this is a bad idea or if you have any other suggestions of how to best go about this process. Also, I have a 10 gallon tank so small deviations in the water are more dangerous to the fishes health. Thanks
