Why are my fish dying?! Plz help

[sc50964]

Symptoms – Velvet dinospores will usually invade the gills first, and sometimes asphyxiate the fish before physical evidence (white dots) appear on the skin & fins.

Does velvet kill fish in a few days? I am not super familiar with this illness.

It can wipe a tank in 24 hrs if it tries, but there are visible signs.

Aha...see I was under the impression that they show up simultaneously.

Did you see any signs of velvet on the fish?

No but our local fish shop who is a veteran in the hobby also believes this is the case. Theyve been included on this journey with us. Also because of the heavy breathing and not eating the day of and before death. And just with the background of getting a petco fish (face palm), it just makes sense.

Velvet - flukes- poor water conditions can all kill fairly quickly. Need pics which I know may be impossible but some history as to things you noticed unusual such as raid breathing, swimming in front of water flow, gasping at surface, flashing or darting across tank, hiding in rocks or corner, loss of appetite, etc.

But that leaves us with the question of why the new additions survive.

Really the only way to guarantee fish are pest free before going into your display is by quarantining them yourself, whether they come from Petco or elsewhere. Disease rates are going to vary from store to store (LFS and big box stores included). I have gotten a number of fish from Petco without issue (and without quarantine, not saying you should not quarantine, only highlighting my point). I think putting too much weight behind the idea that the issue is with the source of this fish is probably jumping the gun. . .

Velvet will kill fish with in 12hrs to 24hrs

Ok, i really am already feeling like it is velvet but after a couple comments im pretty sure. We will go through with this quarentine process. Do we quarentine the fish in copper?

Yes use copper and when you start dosing you will need to pick up a copper test kit. You have to keep up with the amount of copper in the tank

Just in case I want to add, don't put the copper in your display tank! You guys likely already know this, but just want to be sure.

I appriciate the heads up, we have a 15gal we will set up!

We dont have any picture worth showing. All of the fish just look like we pulled them out of the water, and we did as soon as they died. Not to mentio. They arent the greatest quality of pics. I have done inspecting of gills and skin, but nothing i could tell.

Sorry for the length but we really need help!! My husband and i have a 32 gal. biocube. Weve been adding things for a couple months now and have many corals that are doing great but we are having trouble with fish. After having a yellow prawn goby for months we made an amateur mistake and bought a benggai from petco. They both were dead within days with no signs of why. We got a diamond watchman and he did very well for 3 weeks and then died within 2 days after buying a gramma. The gramma did well though, so after 2 weeks then we added 2 clownfish that came with a tank we bought (long story), and the gramma died after a day. We are at a loss. No signs of illness on any of the fish. Only things we know are all the fish stopped eating the day they were dying and started breathing heavy.

I’m not sure I can help, but is there any way something is getting into the tank via your room maybe some type of perfumes or cleaning chemicals or something is making its way into the water?

Stray voltage from electrical? I’m not sure this could kill but could stress the fish?

make sure to run carbon to help water quality. I wouldn’t add any fish to your main tank until you are certain of water quality etc.

I see you had posts for stocking advice just almost exactly one month ago. You also mentioned no water changes. How fast did you add all stock? Typically you want to slowly build up your bio load because your bio filter lags as it needs to populate to eat the new waste, especially in a smaller 30g total system tank. Although it definitely quite possibly be velvet, I wouldn’t count an ammonia spike out of the question.

You’d want to go a single fish for 2 weeks, then add another, the. Possible add twice the mass, etc. with no water changes, no skimmer, very little surface area quickly looking at your scape, you might not have the bio filter capacity as many wasteful stock was added almost simultaneously.

This hobby is all about testing your patience as doing the opposite often leads to disasters.

We dont use any chemicals on or around the tank. We have cats but theres a lid on the tank. Good thought though.

Those are good points, i may not have worded it well but this has been over the course of about a month and a half i believe. Every fish was in at least 2 weeks before adding more but still die almost immediately when a new fish is added.

Yeah, hard to tell from a dead fish unless a skin scrape or sample is placed under microscope. Stray voltage often blamed but fish in essence are grounded.

Take a pic of the inside of their gills. If it’s read and puffy, then it’s either marine fluke or velvet.
