Just wanted to run this by you all regarding my Syno Multi / Grandiops. Took a video today while doing my daily maintenance, if you look right at the beginning of the video and then at the end (I zoom in on him) he has what looks like a "bald" spot on his head, from naked eye it seems ever so slightly raised, but has not grown or changed over the last 2 weeks (when I first noticed it).
Also you may see in the video there are 2 or 3 of them that have similar "bald" areas behind the dorsal fin. Again, this has not changed (from first seeing it) the last month.
Is this something to be concerned about? You may also notice there is quite a lot of chasing going on, they have been like this since they have been in the tank and certainly there seems to be no shying away from any of these guys, they all eat well and are very active.
The tank remains as it has for a long time now at ph 7.6 , Ammonia 0 , Nitrite 0 , Nitrate 10 - 15ppm.
Personally not overly worried as there does not seem to be any change in these areas of them over the last month.
Any comments or suggestions welcome as ever. Thanks Guys
