Help! My Healthy Fish Are Dying

[joyannbuskirk]

Several of these fish type are fairly aggressive. Is there ANYWHERE to hide in this tank or is it just a very small dusting of sand and a ton of fish? If it's the latter your fish are extremely stressed with nowhere to hide or territory to claim. Fish store style tanks aren't designed to keep fish for more than a week or 2

All the rocks will be put back in today.

What size tank is this?

 

[joyannbuskirk]

90

 

[joyannbuskirk]

Okay, rock all back in. Fish are so happy!
Went to store where we but most of our fish. Showed him the photos. He's told us a UV Sterilizer should kill all the bad diseases. Can't install until tomorrow since I put the liquid bacteria in yesterday.

How old is your tank? I might have missed it

 

[fishyjoes]

He's told us a UV Sterilizer should kill all the bad diseases.

This is absolutely not true

 

[Katrina71]

And the Windex cannot be used on your tank

 

[Katrina71]

I am wondering if you have been given really bad advice from the fish store? Looks like a new tank with a lot of fish and a small filter.

 

[Cthulukelele]

Yeah I am having a hard time finding the words. That tank isn't going to handle all those fish off the jump plus they'll create some serious bioload that's going to massively overdo the filtration of that HOB filter.

You should really give some thought to the goals you have with this tank. If I was running an HOB filter for a 90 gallon reef I'd stock it very very lightly. You're likely not getting enough flow either with just the 1 powerhead and no sump return.

Seconding the windex comment.

In that tank with those fairly aggressive fish stressing each other out and a high bioload with what looks like active ich I'd say you're not really starting set up for success.

Lantern Bass: Saltwater Aquarium Fish for Marine Aquariums

That's a lantern bass not a harlequin wrasse. Big difference

Harlequin Tusk : Saltwater Aquarium Fish for Marine Aquariums

Its a harlequin bass, so that's where the name mix up came in.

UV sterilizers will limit, but not eliminate active disease issues.

The damsel fish is breathing really fast and is full of ick, or maybe even velvet. @Jay Hemdal did you see this fish in the video ?

welcome,
glad to have you on the Salty side.

OK 1st off SW fish need more...well of everything than FW fish do. they need more space, more flow, more filtration, more O2

can you run a SW with a HOB sure you can but with real live rock and low stocked.
I think that HOB filter is small for the bio load in your tang, given no protein skimmer or other filtration methods.
kinda looks like you might be using a canister filter? if so whats in it? how often do you clean?

I would brows R2R and see what others are doing to have successful fish only systems. they're not hard but there is a process.
most new comers over stock there tank way to fast. dont have the proper set up and get fish with out research if it will be OK in there take long term with there stocking plan.
most do this. happens all the time.

 

[joyannbuskirk]

So

UV sterilizers will limit, but not eliminate active disease issues.

What else can I do without using chemicals?

The tank is fairly new. It was set up by a local fish aquarium who has been in business since I was a little girl, and we won't go into how long ago THAT was. The owner's son has 20 years experience and I have done everything exactly as he said/says. If he says wait, that's what happens, even though I'm hyperventilating waiting for a new fish!
The tank is cleaned every 2 months and the top filtration system gets changed monthly and the cannister filter underneath, bi-monthly.
We have both filtration systems and an underwater fan to help keep the water oxygenated as well as a good flow.

We did NOT have a problem until the introduction of the Diamond Back Gobies.

 

[joyannbuskirk]

And the Windex cannot be used on your tank

Okay? Why not? Just asking, no offense intended.

 

[joyannbuskirk]

All the rocks will be put back in today.

Don't sweat a few losses. Just wait until Thanksgiving time before you add more fish, do a weekly water change, and put that UV on tomorrow after the blue fishie dies.
