snails add to biodiversity. I like my ramshorn snails and my briggs. In my 38g lowtech I have nerites, ramshorns, briggs, and probably soon to have pond snails. I feed my fish sparingly 4 times a day. I am sure the cherries are second inline for food and the snails 3rd. I never have a problem with over population. If I see that snails look on the abundent side then I just pull a few large ones out and toss them away.
I raise my sword in the air in the battle against clado. I have been beaten in this battle but the war is not over. As my wounds heal I amass another army, an army with many legs, an army of Amano's......
I thrust my tridant into the mass of medusa like staghorn. I am wounded but I refuse to take a knee.
