both of the above stated do par possibly sub par jobs of algae removal. In a tank with large leaves like that you would want to have bristlenose, otto's, and nerites snails. The nerites are able to get on these such leaves because they can support the weight of this snail. For fish you definatley want ottos and bristlenose.
