I just started my first marine tank around two months ago. I have 2 fish: black molly and citron goby, no corals.
Last time I checked parameters it was ammonia 0, nitrite 0, nitrate 10-20, temp 25-26C, salinity: 1.022
I had molly for over a month and I added goby around 10 days ago. The next day I noticed two things that worried me:
1. On the second day after adding goby to the tank (so about week ago) I noticed a dark spot at his bottom. I can't tell if he was like this when I put him into the tank or not. That's the best photos I managed to take today:
Not sure if relevant, but when I zoom I can see lots of tiny dark spots on his skin, you can't see it with naked eye. Unfortunately I didn't manage to take a good close up photo of the dark spot, so not sure if it's the same thing:
That's how it looked on the day I noticed it:
Is this Hyper-Melanization? I asked the guy from LFS what it is and he said he wouldn't worry about it, but didn't tell me what it is. But I do worry, hence the question
2. While I was observing him I noticed another thing. Small white spots. Again, I can't tell if he was like this when I put him into the tank or not.
I noticed it on the on the same day or a day after I noticed as the black patch tank (so about a week ago). I went away after day or two, but now I can see them again.
Is it marine ich, lymphocytes or something else?
Below some videos where you can see the black patch and also small white spots on his fins:
Video 1 (week ago):
Video 2 (week ago):
Video 3 (today - it's more stressed after I was trying to take a good photo of him for a while):
It's my first fish so I can't tell if he is acting normal or not. I didn't noticed anything too worrying. It is a bit scared sometimes and swims away as soon as I come closer, but sometimes doesn't seem to be bothered at all. Maybe a bit of heavy breathing a bit heavy especially after feeding, but I can't tell if it's normal or not. I didn't noticed any rubbing against rock. It eats ok, sometimes spits out some food, but I assumed he just didin't liked it.
It's my first post so applogize if it's too little or too much info or I forgot about something.
Thanks
