Hello I am new to saltwater fish tanks and I've had my tank for about a month and a half now. Everything was going perfectly until yesterday when I noticed my pink spotted goby acting very lethargic. I added him and two juvenile clowns about a week and a half ago. That's was after my green chromis had been in there for about two weeks.
Anyways, yesterday my goby was fine in the afternoon but when I looked in my tank later that night and he was laying on his side and breathing very rapidly. Occasionally he would swim very jerkily to the top of the water and bite at the water surface. He eventually perished soon after, maybe an hour after I first noticed him laying on his side. I was unable to do anything since my lfs was closed other than test the water and do a water change. My tank and water parameters are as follows:
Ammonia nitrates and nitrites were all zero/undetectable
KH was ~9-10
pH is ~8.3. temperature 78 degrees. Salinity 1.023.
It is a 20gal tall with a fluval hob filter, a hob protein skimmer, and a 264 gal/hr power head.
So my goby died last night while the rest of my fish were fine. Then this morning I check the tank and one of my clowns was showing the same behavior as the goby, laying on side with heavy breathing and discoloration. I rushed to the lfs and got stuff called paraguard that is sort of a cure all for fish diseases. But by the time I got back my small clown had died as well! My green chromis and other clown seem fine and are eating normally.
I don't know what's going on but I'm assuming it's a disease spreading around since my water parameters are fine and the remaining fish are fine. I saw no white spots or film or cuts on the sick fish, just discoloration
My question is should I use this paraguard on the other fish just in case they have caught it too. I don't have a qt tank but could set one up since I have an extra 10 gallon tank.
tl;dr two of my fish have died in my 1.5 month old tank while the other fish are fine. How do I save my other fish? Is it brooklynella?
