My fish are dying! Help!!!!

Big C

Guest
Hi, I'm new to this forum business. My daughter signed me up, after seeing my frustration with the 30g tank she gave me for my birthday last April . After several months of trial and error I finally got it going with 12 happy fish. Someone convinced me to change the plastic plants for real ones. Did that with the advise of the local aquarium last friday and now I have half the fish and all the others are not eating at all.

Last night my clown loach (Big C) died and it made me really sad. It was the oldest fish I had (8 months!). The only advise I've heard so far is "let them be. They'll come around". I'm just watching them die!


Don't have a test kit, but took samples of water on Saturday and Monday to the aquarium. On Saturday they told me that the nitrates were slightly high and that may be the new gravel they sold to me had some toxins (!). And to do a WC of 40%. I did. On Monday water quality was good. I changed 10% yesterday again, just to remove the food lying on the bottom of the tank.

I have left: 1 denison barb, swimming around but not eating. Two gouramis, one very letargic, the other one sort of eating. One pleco, who will die on me anytime because, he is in a total hungry and swim strike. And two little marigolds (I think that is the right name). Only one of this little marigolds, have a couple of white spots on the top part of the body. Look like fungus. But the other fish are only letargic. I also have 4 ghost shrimp that we bought with the plants, last friday.

The clown loach was only a little whitish, other than that he looked fine.

The water is sort of cloudy, but it's been like that for a few months, and no water change or scrubbing can get the cloudiness out.

Because the first casualties were immediately after the changes (8-10 hs after) I think it has something to do with the gravel. I washed it for 10-15 minutes under running water before adding it on top of the old gravel.

I thought of changing it all again. I know that more changes would probably cause more stress, but it looks like they will all die anyway.

I hope you guys understand how sad I feel. My family thinks: "It's only fish!!"

Thank you! :(
 
The most important thing here is that you must get a wter test kit, witout knowing what your ammonia, nitrite and ph levels are is going to be wild guesses all round.
The cloudy water is probably down to a bacteria bloom. I'm no expert, thats just my opinion.
 
How much are you feeding? If your nitrates are high and the water has been cloudy for months then I suspect this may be at least part of your problem.

Also, from the looks of it you have too many fish in there, the plec for starters is a bit too big a fish for that tank. The waste exhumed from them alone can be substancial, let alone with that many fish with him.
 
I'm feeding a lot less than before the changes. But until then the fish were eating all the food in a minute or two. The pleco is really small. Of course I learned today that they tend to grow quite large, but nobody say that at the fish store where I bought it. All the fish were happy and eating for months before last Friday.

1denison barb,
2 gouramis One pleco
2 marigolds
4 ghost shrimp that we bought with the plants, last friday

Thank you!
 
Don't feel bad C, most lfs give horrid advice and know stuff all about the fish they sell. Important thing is you have found us now and we can give you good advice (well, most of us :lol: ).

Do any of the fish have fuzzy white spots on them?

How often do you do water changes? Also how much do you change?

Do you have a second tank handy in case you need to quarentine some fish?

Do you use a declorinator in your water?
 
Thank you! I'm sure glad I have someone with whom I can share my "fish sorrow".

Just went to the aquarium and bought a test kit. The results are all "safe":
NO3 40 ppm
N)2 0
Hardness 120
Alkalinity 80
pH 7.2
NH3 .25
Water temp is 80F

I was doing 15-20% WCs every week. Since last friday I've changed 40% on Sat., 10% yesterday and 20% today. I always use conditioner for the chlorine and mix it very well with the water before ading to the tank

One of the marigolds has white fuzzy spots (like fungus). The pearl gouramy is becoming whitish all over like he is sheading (?).

I don't have another tank only a small fish bowl.

Thanks again! :dunno:
