#molly

My little brother bought a pair of Orange Mollies today, when I looked at them I saw tiny black dots on their body and fins. I've currently put them in a quarantine tank. I just wanted to know if my other fish will start having problems if I add these to my main aquarium.

I have one swordtail that keeps getting chase by my platy every so often all over the tank both are males. I am 99% sure is because the swordtail keeps chasing after the female platy that the male platy chases. I know that both species of fish can cross-breed although I am not interested on it...

I have a black molly with ich and unfortunately I don't have another tank and unable to buy one due to financial issues. So far its isn't bad the molly doesn't seem too disturbed, not even with other fish, he still eats. He is in a 60 gallon tank with 15+ fish, who don't seem to have ich I have...
