Mystery or Not????

[mbscuba]

I upgraded my 40g to a 75g. I brought over a Cole Tang, Bangai Cardnal, Bullet Gobby, snails, hermits, and coral. Everything was running fine for about 2 weeks. Then it started. First my cole died. I went and bought an anthias. It strted getting sick, and died. Then my gobby was getting real ill, and died. I kept checking parameters, and everything was at zero. No NH3, NO3, or NO2. Ph was 8.2. I even tried water changes. My Cardnal is as healthy as a Lion. All my snail, hermits, Corals, brittle star, banded coral shrimp are also perfect. I desided to get some more hardy fish. Put in two Chromas, and a clown (Nemo). The chromas are great, Nemo passed after 2 days. Is it a mystery, or just my luck and got bad fish. Keep in mind I've had the Gobby for 5 months. Could there be a Toxin in the water, that can't be tested, and only harms some animals?

Any help

Thanks

What is your SG? Water temp? Some of the fish you mentioned are hard to keep and feed. Anthias and Tangs can be tricky. Stick with the hardy fish for awhile. Tangs need lots of food and places to hide. Have you bought all the fish from the same place? Is the water you are using for water changes been tested? Many fish are very sensitive. To water params changes. Check all of that. Good luck.

Depending on the supplier the fish are hit or miss some, live some die. If you get healthy a fish, agression in a small tank is another problem. A new fish healthy but stressed from the move will often die when other fishes chase it around the tank and beat up on it.

In many ways fish are like street gangs and will not allow the new kid on the block to play.

What test kits are you useing? How old are they?

What looks ill about them, do they have white patches on them?

I like to think that fish have a lot more dieses then we know about. escpielly aquaculture those places are like prisons fish all close together dieses are esailly passed. Another thing i think of is imbreeding after a while its gotta be slim pickens for desirble healthy fish to breed so the same ones are used continously and a lot of pairs are made from the same brood>

i dont think many fish in the hobby are inbred shovel, seeing as almost all come from harvesters in sri lanka or other parts of the tropical indian and pacific oceans. maybe the hillbillie fish from arkansas, but not likely the problem here.

stop adding fish till your tank stablizes.

aggression is a strong possibility and so is reliability of source.

+1 for SG. some fish are more sensitive to salinity than others.

cool it on the water changes, let the system stablize.

How are you acclimating the fish? How long has the tank been set up? What are they eating?

SOunds like you had a small cycle take place. How old was the 40g before you went to the 75 and how old was the 75 before things started to die?
