need help from some Silver Dollar owners. i saw some at the lfs today and they are soooo cool looking. my cousin owns a couple of them; loves them but says they will destroy any live plants in your tank. however, the lfs employee said they only nip at dark leaf plants. my cousin only had one type of live plant & they ate it. all i want to know is will they eat all types or most type of plants? my signature line shows what type plants i have. can someone please let me know asap. the lfs said they will not be getting any more for a while and i want to go purchase now but it's going to be based on the feedback here. thanks.
