diagnose

Had this Blenny for about a week now and I check on him daily, today I noticed this large ball on its fin. Any ideas what this could be, should I isolate it is it contagious, treatment ideas? Anything helps photos below thank you!

Hi, my three spot blenny suddenly stopped eating today and hiding away in its little cave. It was breathing hard so I thought of ammonia rise. Did 20% PWC. Later on, it came out and swam like frenzy, almost hitting itself to the substrate. In that instant, I thought he was a gonner. I decided...

Hey! So I’ve been on quite a journey with my mocha clown I have him in qt with my frostbite snowflake, the mocha showed signs of Brook gave him a bath in rrr and treated tank with metroplex, once again after a couple weeks showed signs of Brook and had this worm like string coming out of him...

Hi about 3 days ago these zoas stopped opening up all the way and looked odd maybe deformed. The tank is fairly new maybe a little over 4 months now, so these zoas we're still growing on the plug. I noticed that there was a couple white sponges growing on the back and the side of the plug as...

I went over to my tank to take a look at whats going on and I saw my YWG outside of his cave and he had a fairly large white spot in front of his dorsal fin (shown in picture (sorry its bad Ill take another one later on today when the lights go to normal)). I really don't want to loose this guy...

So I just got these mocha vinic clowns last week. They seemed to be doing well, and eating. On eats and spits out the pellets or just eats the tiny stray mysis legs that float around after the others demolish the mysis. So little to no nutritional value. However, today I actually REALLY watched...

Hello, A couple weeks ago I posted about my Tang looking for a diagnosis. It was concluded to be the start of a bacterial infection. I started dosing kanaplex which has definitely helped. I was advised to give a better diet, the infection is almost cleared. However this has kept up at first it...

I've had this guy in quarantine for about a week and noticed this developing a couple days ago. Any clue as to what it is and how to treat? He is eating fine, but every now and then he kinda flex curls to that side, so I think it's agitating him more.

I've lost an emperor Angel and a Singapore angel so far I'm treating my tank with metroplex and kanoplex and binding with focus in their food, as well as using the fishkeeper. I also have a blue Tang, foxface rabbit and a blue spotted puffer. The fox face and blue spotted puffer showing no...

Just got this little juvenile Emporer Angel last week. I got him with a baby Royal Blue Tang who was very sick. I got the tang to try to save him because he was very malnourished and had some kind of infection on his body. They both had parasites. The water in the bags from the LFS when we...
