I just recieved 8 silver dollar from craigslist for free. I never had this kind of fish but i had a red belly pacu before. My question are,
1. What is they best pellets to feed them?
2. Can they tolerate a little salt in the water?
3. Can i add a tiger silver dollar with the group?
4. How hardy are this fish?
5. How can i train them to eat lettuce?
They are in my 180g tank, tank mates are all bichirs, so they have all the top and middle to them selfs. I have two that are 4" and six that are 1" in my grow out tank. Is it ok if i add more of them? Any info can help. Thank you
