Iv been half heartedly trying to rehome my silver dollars , no rush just changed my mind on them and slowly looking to move them on . Iv been offered a swap of a snowball pleco for the 5 , money comparison doesn’t really interest me but the bio load does main reason for getting rid of them is they are greedy and very waste full and feel my tank would sit a lot lower no3 without them but would adding a snowball be just as bad ? Surely one pleco isn’t as bad as 5 silver dollars ? And also I have a green phantom pleco , would they fight ?
