Found dead fish this morning!

[Bsvenonius]

Tank has been running about 3 months. PH is at 8.2-8.3, salinity 1.025,ammonia 0, nitrate 0, nitrite 5, temp 78. Woke up this morning and found 3 dead fish... all intact just floating at the bottom. One 5" lawnmower Blenny, one chromis, and one dwarf angel. Any ideas would be great thanks!

Any other inhabitants or just the 3 dead ones?

 

[MrNurse]

How long have the fish been in the tank?

 

[Tripod1404]

nitrate 0, nitrite 5 or you meant the opposite way. 5ppm nitrite would be pretty toxic.

 

[Bsvenonius]

Yes I wrote that wrong sorry. Nitrite 0, nitrates at 5. I have a leather coral, torch and hammer also that I did not mention(didn't think I needed to) . I have two small crabs and a cleaner shrimp. A HOB skimmer that seems to be doing the job, and a vortech mp10 pump on short pulse mode. Everyone seemed happy until this morning. Chromis was around two months,the blenny and dwarf angel about a month.

 

[Tripod1404]

How big is the leather, they sometimes can release toxins to the water.

 

[Bsvenonius]

It's a double head. They are both around the same size, 2" in diameter. I have a 38 Gallon tank with T5 bulbs on 8 hours a day.

Maybe the fish were added to a tank that wasn't all the way cycled yet. Tank 3 months reef chromis 2 months. Plus 3 fish two crab shrimp coral small tank and not a efficient skimmer. What are the water changes like? When was the last water change

 

[Bsvenonius]

Last water change was 4 days before I found them dead.

 

[Bsvenonius]

I change the water (10 gallons) every other week

People need to learn that in this hobby nothing good happens fast.

I know we all want to see the lovely fish and corals in our tanks but one must refrain until the tank is cycled then slowly add one at a time over a long period of time. This saves money, time, and most importantly the live stock.

Slow your roll good things happin.. Haste makes waste..

 

[Bsvenonius]

Ok so what are you suggesting pond boy because this really didn't help me. i cycled my tank for a month , then added some small coral frags and three fish while doing water changed every other month. So what do you suggest .

Found dead fish this morning!

Any damage to the fish?

Are you running carbon? When was it changed last? How much?

Was the water clear last night?

Any long stringy poop recently?

Any spots on the fish?

What size tank?

How much live rock? Was it dry rock?

How much sand? Was it live?

How did you cycle the tank?

Slow down did you read my first post. Not trying to offend you, when you add that much bio load to a new tank you are headed for disaster... Like I wrote before add the live stock slowly..

 

[Bsvenonius]

No damage to the fish , no carbon on my 38 Gallon tank just a skimmer, water seemed clear last night, my dwarf angel had a stringy poop but then detached . No spots on the fish that I could see, some live rock was added and some dry rock when I cycled my tank while adding seachem stability, 40 lbs of sand and about 25 lbs of rock(15 live).

 

[homer1475]

I would assume none of these fish were quarantined?

It's hard to say for sure, but since your coral and inverts are still fine, ammonia poisoning is unlikely at this point.

IMO 3 small fish and a couple inverts in 2 months time on a newly cycled tank should be fine(assuming they were not all added at once).

Also IMHO that flame angel would have become a real d*ck once he grew up some. I have one that was a model citizen in my biocube, moved into a 90 and he rules the tank.

Could there be a power outage last night and fish suffocated?

I feel your pain!! I've done everything! And still all getting dead fish!! I have 85L/ tank, no coral, 6kgs of well cured live rock, tank cycled for 2 months, all water parameters hood, amm0, nitrate5-10, nitrite 0 salinity good, pH 8.3, added 1 chromis, 1 yellow tail blue damsel, they hid in tank didn't take food a week later dead, checked water, ammonia spike(small), left tank, to cycle again for another month, all good again, added 1 chromis, 3 days later it was sick, put it in 20L tank I had trialed before bigger one, it recovered, put it in big tank, 24 hrs dead, half water change, cycled again, for a month, added 1 damsel, water parameters all good, 3days dead! Water parameters still spot on! I have no ideas

 

[Glennoh1811]

I also have internal filter 550L/h,for water flow, plus 1800L/hr filter with bio beads, I just cannot work out why I'm losing fish. They all hide and don't take food, then die in 3-7days??????????????????

 

[JustinM]

Homer had a good question, did you Qt any of the fish?
