Looking for input on what may be going on that my gem tang just stopped eating. I got him about 10 days ago he has been in 20 gallon QT doing TTM. Qt was medicated with copper power (2.6ppm). He was eating frozen like a pig, fat and happy. 2 days ago he stopped eating all together. I have not...

I’m not sure if this is urgent or just the fish warming up to the new tank but one of my new clowns is looking bloated and is only sitting at the bottom of the tank, breathing heavily. I only just let them out of the holding box after letting them get to know my other fish that were already in...

Hello. I have a newly set up tank and started with a filefish. He was doing well for about a month and then we added two clownfish. The tank is 26 gallons. The filefish mysteriously disappeared. Mind you the ammonia and nitrite had been zero before we put the fish in. Two days later one of the...

Hi all, I recently bought clownfish for my birthday. I have two in a 20Gal tank. I have the tank already cycled. The parameters (nitrate, nitrite, ammonia, pH 8.5) for the water were all 0ppm when I added the fish. I noticed one week in that they were dashing around and acting erratically...

My cardinal fish had one cloudy eye yesterday evening, I checked my water and nitrates were a little elevated so, just to be safe, I did a 50% water change. He was also swimming very close to the bottom so I put him in this tank that is meant for baby fish to avoid him being eaten by my...

My female clown has this strange little red mark directly below the dorsal fin on both sides of her body (pictures above.) Is this an abrasion or some kind of bacterial disease? She’s acting perfectly fine and I don’t see it in any of my other fish.

Hey fellow Reefers.. although im not a reefer yet, just an aspiring one, I have a freshwater aquarium which I am using to learn ALL (!!) I can about to graduate to a reef so I don't mess up. But now seems that im messing up! Now in the last weeks one by one my fish are dying off.. why?? Fluval...

I have an otherwise healthy puffer that's about 5 inches long that just started showing these spots on his back today. He was perfectly fine yesterday and was eating with his normal huge appetite. Water parameters are normal and all his tank mates are not showing any signs of disease. He's been...

Super new to the hobby. My narrow-lined puffer has what looks like a sore on his mouth. I tried my best to get a photo of it. I have a 125g FOWLR my tank cycled for two months with only live rock and live sand. End of month 2 I added a pair of clowns. Four month I added zebra eel (2 feet long)...

I bought this copperband butterfly from Liveaquaria. It came with a white big spot in its back fin and one side fin. After one day he is showing more but they look a bit different that ich. They are bigger. Do you have any idea what can it be and what should I use? I have to say he is eating...

I have to quarantine all my fish because of Ich. My Naso tang is showing this white line. Do you have any idea what could this be? Naso looks super skinny.

Hi guys, I'm really concerned about my clownfish! 2 days ago I woke up and there was a missing spot in his tail fin.. and this morning its tail is almost completely gone and its right fin seems hurt too?!?! What can possibly be happening to the fish? I don't think I have anything in my tank...

My branching frogspawn has been growing, but also has whitish spots on it. The spots have me rather worried. Is this bleaching? An illness? Or could it be completely normal? I'm a total newbie to salt water and finding my way. Parameters: 29 degrees Celsius, 1.025 salinity, 8.2pH. Low flow...
