silver dollar

Hi everyone. I have a 75 gallon freshwater aquarium, 7.0 pH, nitrates less than 10ppm, 0 nitrites, 0 ammonia, everything is clean and well balanced. I do add some aquarium salt when I do my water changes. I have a 5 year old female silver dollar that began developing a pea sized lump in her...

Thanks in advance for help on this problem... Information: My two silver dollars eat everything I plant in my 29g. of course, and I have a nitrates/algae problem, of course. Letting the little rascals go to another home is, of course, out of the question: they've been with me so long I couldn't...

I am thinking of starting a 65-75g tank with a small school of silver dollars and maybe some tank mates. I have had some experience with freshwater fishkeeping, but i am no expert. Im also hoping I can make a nice looking environment in the tank without breaking the bank. 1. Is 65-75g enough...
