I have a 5" oscar that lives with a couple of tinfoil barbs, catfish, pleco, and jack dempsey. I've had all of these fish for about 2.5 months now and all are eating aggressively and are very active. Two days ago I noticed little white dots on the jacks and oscars fins and head/near eyes. My water levels are completely normal. I watched them for awhile and it seems as though the dots come and go as they please. What is this?
No one's behavior or eating habits have changed. No rubbing against anything or swimming sideways. No loss of scales, normal appearance all around (except for the dots of course). Am i just being paranoid?
