help with my fish stock

[jamescon85]

Hi all,

 

So i have had my tank for 6 months now, i have had a firefish, chromis, and 2 clowns pretty much from day one. I then added a scooter blenny and he has been fine for months. I then tried a couple of dwarf angels (bi colour and coral beauty) and both lasted less than a week. I have recently tried both a goby and a blenny, which have also lasted less than a week, however i did introduce a cleaner shrimp which has lasted maybe a month now. Does anyone have any idea what could be going wrong? is there a rogue fish in there destroying new comers? my parameters are fine,do 10% water change every week and half, and still have all the fish i started with aswell as the scoote blenny. At the weekend gone i just added a small six line, he seems fine so far and isnt attacking anything or getting attacked himself, fingers crossed he will be ok

What size tank?

[lkoechle]

what are your parameters?

Your other post last week... you said your clowns had white spots.... sounds like your tank is infected with ich.

[jamescon85]

Clowns all cleared up. That could maybe be the cause but surely it would have affected all the fish? I added some cuprazin to the tank and that cleared it up and I now have a uv on there. Tank is 140 litres. Salinity is 1.022, and ammonia and nitrites both at 0, with nitrates between 0 and 5ppm

Just wondering if you quarantine your fish? Ich can hide sometimes and not show up until the fish is stressed. I also just read about a strain that is copper-resistant and kills in about 24 hours.

Nope I don't, however I buy from a store which do quarantine and they also have uvs on all their tanks. I have no spots on any of my fish, and haven't had any on any fish other than the clowns, which cleared up with meds

IMO your salinity is a bit low. I like about 1.025-1.026 also don't do a drastic swing 5-10%weekly water changes are good.they say ick Is present but it shouldn't bother healthy fish in a healthy system. I would look at the system before I started adding chemicals

[jamescon85]

the reason i have my salinity at 1.022 is because the shop i get my stock and water from has there water 1.022, and they have kept fish there for months with no problems

I added a flame angel to my 20 gal tank a week ago. I have a damsel fish, black sailfin blenny, ( who lunges at him occasionally) Percula clown and a possum wrasse. He seams to be stressed a bit. It may be a pecking order problem. I wonder how these fish are collected also from the wild. That may have some influence on how they adapt to an aquarium. I kept a pygmy angelfish in the past in my 29 gal bio cube with success. BTW my tank is a mixed reef which is why I keep my salinity where I do.
