Ok, that makes sense. I understand that having the shrimp/snails is helpful and important, I just don't want to be removing lots of snails and killing them, or constantly buying new shrimp if they die. It's not at all that I don't want to do the work, I just care about everything no matter how small or seemingly insignificant. Would a Mystery/Apple Snail work? I have had those and they aren't a problem for me at all, and in fact I enjoy watching them. And as far as the shrimp go, how many would be needed for a ten or twenty gallon tank? Sorry for all the questions, I just want to make sure I know what I'm getting into before I attempt this.
Kindness and respect should be shown to all animals, no matter if they are furry, scaly, big, or small. Be a hero to the animals and GO VEGAN!
