I noticed some strange discolored marks on my t cup rays they are about 5 inch disc.upon closer exam i could see a small flat,bug with legs.i took the rays one at a time and removed the bugs with tweezers.The first bug was twice the size of the other and came off easy the second seemed to be hanging on like a tick and i had to pull it off.Would these bugs kill my rays,could there be eggs in the tank or baby bugs because there were two?Is there a way to kill these bugs without physically removing them with tweezers?did i do the right thing removing the bugs?
