I’m generally someone who does a lot of research when I have a question, but I’m genuinely stumped and need to reach out to y’all.
I picked a clown up three weeks ago to pair with my current clown. I have a 10 gallon so they were the only fish and I’m personally a believer that all fish from stores harbor disease / healthy fish manage or beat disease / QT over stresses and temporarily weakens the immune system so I acclimated it then put it in. That’s not exactly the point of this post so I won’t really get into it. I’ve been to the store several times over a month or so and saw the clown every time, swimming and eating fine so I figured it was healthy.
It took right to my other clown, and has acted as any clown would over the past few weeks - eating way too much and thinking anytime I looked at the tank I was going to feed it. The more I looked at the fish, I realized it had a clearish, ovular spot right behind its pectoral fin. I figured because the fish acted fine, it was just some discoloration. You can sort of see it in the first picture - apologies because this was only a screenshot of a video I took. Two days ago I was rearranging some coral and rock structure, and obviously the fish was scared at the time. Yesterday, it spent all day hiding or swimming in spots with low current. Today, it spent all its time doing the same - until I found it stuck in the intake of my RFG. There were some scales that looked like they were either worn down (from resisting the RFG) or clear like brook on the lower half of the fish and a little patch on the nose. In the second pic, you can see the spot, but the blue light makes the spot appear much more drastic in comparison to the white bars.
Anyways, I just noticed a similar clearish patch on the other clown in a similar spot. The dang thing never stops moving so that picture is about as good as it’s going to get.
What is going on? I thought that most diseases present right away if harbored by fish? Certainly those that are deadly, that is. Nothing I look up brings any similar results. The deceased clown had been fine for weeks with exception to the odd looking area.
