It is hard sometimes feeding them worms with the tweezers some times they slip out and they fall right between the rocks. I have one filter bio 350 marineland filter with some sponges shoved in the outtakes to slow down the water and helps with the bio i suppose, also i have filter u can place how ever much carbon, zeolite crystals what ever i want to place in their for extra cleaning. It is also hard the use the gravel cleaner in their to put price u have to pay with plants everywhere.
I like the moss walls people are building and i thinking of making a coupling to put on the floor instead of the wall with holes cut out for prearranged plants. Just an idea for anyone!
