High likelihood, may be nitrates as they produce a lot of waste. Its important to have an effective filtration system to keep their water clean. These sharks are also susceptible to bacterial and parasitical infections and rarely tolerate high nitrate levels.
All my fish are good and swimming. It’s just the sharks, eyes are red and have a hole in them. They still are eating . I’ve done water changes.
Ph 7.8
Ammonia 0
Nitrite 0.25
Nitrate 5.0
Use ro water
Salinity is 1.025
I used a ph buffer a few days ago to raise the ph then a day later this happened, I was told it was ok to use it with them in the tank
I’ve had them for 2 monthsSome follow-up questions:
How long have you had the shark?
What is the water temperature?
What fish are in with it?
Is it still eating?
I’ve had them for 2 months
They are eating I have a tangs/file fish/ fox face/longhorn cow fish , and a assortment of angels
I have a lemon peel/ emperor/singapore .Depending on the species of angels, they may have picked the eyes of the horn shark. Pomacanthus angels are the worst in that regard.
What is the water temperature?
76 on temperatureI have a lemon peel/ emperor/singapore .
I did notice the file fish nip at one of the sharks eyes yesterday but they haven’t messed with the sharks before. I have two sharks and both of them have ruptured eyes
76 on temperature
And assumedly the higher temperature is 1) a risk for infection - stress, and 2) faster growth of the infectionHorn sharks do best if kept long term below 72 F. 76 is o.k. for short term.
I suspect mechanical injury to their eyes from tankmates, possibly followed by bacterial infection.
While this shark has a natural rough skin texture I wonder if bacterial issue on hand and again reverting to water quality and elevated nitrates. Buffer too may have played a role.
Both eyes have holes in them, anything I can do for them or will they not recover. I’ll take some water in and have it tested. The owner of a fish store here had stated the buffer would be ok so I’m hoping it’s not thatWhile this shark has a natural rough skin texture I wonder if bacterial issue on hand and again reverting to water quality and elevated nitrates.

I encourage you to take a water sample to a store that does NOT use Api kits and have them test your ammonia and nitrates and compare readings- then you'll know where your levels truly are at. Also you can disregard Nitrites which is freshwater specific
Hopefully not retina damage. As for treatment, they are scaleless making it more difficultBoth eyes have holes in them, anything I can do for them or will they not recover.

I’m sure they are damagedHopefully not retina damage. As for treatment, they are scaleless making it more difficult
I believe they are tolerant of Kanaplex by seachem
