My blenny die, help, plus advice on how to keep my fish fine.

[loveaddressbox]

I'm really upset, sad and guilty.
Why? What happen to the blenny?
Was eating just fine, just eat yesterday, was swiming around everywhere in the tank sitting on the sad and randomly bite the sand or rocks.
Just beautiful, never show to be sick or anything.

I take a picture so maybe you guys can please tell me what happen.

I don't want any of my other fish to die.

My tank and information:
30Gallons.
1.021
75.2F

About things like NO2/NO3 I got it tested at the local fish store and I had nitrates (NO3?) and phosphates, but the guy say those was on safe levels.

I got the fish as a gift on a mail box that a friend sent me.
So, not that I could give them back and wait for my values to be perfect.
Fish list:
1 Nemateleotris Magnifica
2 Elactinus Oceanops (They hide all day on a rock and throw sand outside, can they be aggressive to others?)
1 Cryptocentrus Cinctus
1 Pseudocheilinus Hexataenia
4 Chromis Viridis
2 Amphiprion Ocellaris

I had more... But... I went taking them to a local fish store and got filter cartridges and free advice in exchange... I didn't really look for more than having the fish on a safe place since the Pseudochromis I had wont stop chasing everything, so I take all fish that seem tobe fighthing and give them to other people or a fish store.

I fear that there's something on the Live Rock... Like a crab or a shrimp.
I set a couple of traps but didn't get anything (Home made water bottle trap)

Nothing even tried to get in I suppose since the fish in there was whole.

I also had nori sheets that I put in the morning and remove when got home from work for lunch. But no one bite them either.

What I'm doing wrong?
Help please.

I'm not sure that anyone here can tell you why your fish died based on the information you've provided, but there are several things that stand out as possible issues.
1. How long has your tank been established? I'm gathering not that long based on your chemistry levels (although knowing numbers instead of "safe" would be helpful).
2. Did you add live rock from another source and that is why you are thinking there might be a crab or shrimp in your tank of which you are not aware?
3. Did you quarantine your fish?
4. Your tank seems WAY overstocked for a 30 gallon. By my count, you have 9 fish not counting the one you lost? And you've already taken back or given away other fish? That amount of livestock alone could count for water parameter problems.
5. What kind of filtration are you using? You mention filter cartridges so I am wondering if you're using a hang on the back filter system?

You might want to try asking the same question in the New to Hobby section as I think you will receive lots more responses on a situation such as this.

Good luck!

Are you still having ammonia problems? Did you finish cycling your tank? You never came back and answer me on the other thread. I'm trying to help you to stop killing things. And YES you have too many fish in that small of a tank. That will cause ammonia spikes if you don't have enough live rock and bacteria to process the fish waste. This is probably what is going on.

Isn't that a lot of fish for a 30 gal?
And I don't see any algae on those rocks...

About the first days of October, was when I add live rock.

I just come back from the fish store and he read 0 on everything basic (NH3, NO2, NO3)
Thought I was there when the test was done and in my opinion NO3 would be on the second side of the strip 20-40 and not 0-20 as the local store guy say... But I don't see very well without my glasses.

Also he has one of those machines that look like... Refractometer? 1.023 and my densimeter is 1.022.

No, haven't add live rock since it was sep up and when I buy the first corals about a month ago. I just think of the evil hidden pest on the rock because... I run out of possible ideas...

No, I don't have a quarentine tank.
I just had plans to add about 3 to 5 fish when I get a sump and thought of using the sump tank before it was connected to the tank as a quarentine.
But I get the fish as a gift before I thought... The original idea with this gift box was that I would get some beautifully colored rock (with calcareous algae) and I was getting some macro algae.

Yeah... They are a bit too many, I have been trying to find them a home, but is hard,
The tang and some others was easy to find home, but no one wants the Chromis, only people with more aggressive fish or really new tanks.

Yeah, I'm using a Marineland?* Penguin something...

I find out what happen, the water was very hot, the heater isn't working, it "stuck" and heat the water to an I supose... Dangerous temperature.
I find that out when I put my hands in to remove the the dead blenny and the water seem warm...
The termometer is not working I would say.
The corals look beautiful today thought

Thanks for the good luck.

Not that I know.
It appears it finish cycling, the weird algae that covered everything went away, now there's just some "normal" green algae in some places. The fish bite it all day.

I forget I had to reply, sorry.

That is a bit hurtful... I never... It has just been this time and it was a manufacturer mistake. I do feel bad about it, I worked on getting the heater working fine and it had days working fine.
Just last night it seem to stop working properly. I do have been a bit inactive because of issues I can't control, but I check the tank all mornings and nights, no matter how I feel, I don't take any life lightly.

I didn't keep all the fish, today I was able to give away some other Chromis.

Seems like there are a lot of issues that need to be dealt with. Your salinity is off, should be 1.025 and your temps should be 77-78 degrees F. Live rock provides invaluable biological filtration.

Tell u what I think .it starved to death.i had one when my tank was new and growing tons of green thread algae.i bought this blenny and it went to town and eventually cleared every last scrap of algae.ripping off huge chunks.it got so fat it could hardly move properly.once all tha algae went it gradually got thinner and thinner.it would even look at any other food that I fez the other fish with.after a couple of months it passed.if u cycling a new tank,don't panic when u get all these weird growths,it's distressing but natural and it does die off eventually.hope this helps someone.
