Help! suddenly tank is killing everything.

i have a tank that i put some cherries in, they died in 24 hours. did a water change check parms (100% fine) put more in .. died 24 hours.

this tank had a betta in it. i moved it to a bowl when it ate it's fins and as the betta seems to like the bowl threw some shrimp in..

i'd like to put some fish and shrimp in there but i can't figure out what is going on. i've done at least 3 80% water changes in the last 2 weeks.

this has been going on for 2 weeks.

i have purgen in the tank for the last 48 hours.

i have tried with UV on and UV off.

added some extra prime, and stability... same thing.. shrimp dead within 24 hours.


ANY IDEAS...

0 nitrates, nitrites, ammonia, 130ppm hard, 7.0 ph, ... really water tests 100% fine. tank does have some alge just regular green fuzzy stuff on drift wood.

oh, the shrimp cleaned all but one spot on the drift wood .. not one shrimp touched that spot (odd)


on the plus side my plants look pretty good.

(oh, i HAD co2 in the tank, but as not much was going in and it wasn't making a difference i stopped it 1.5 weeks ago)

1 6 gallon
1 2 gallon 8" cube
1 10 gallon endlers tank
1 betta

you can see more photos here the 4 8" cubes are on flicker... will get to their journal at some point (they are fun as they change often)

Something definitely doesnt seem "fine" no matter how many times you use the word.

if you are keeping dwarf shrimp, the mastery of GH/ KH and PH is compulsory.

Your Betta is a high 70/low 80's loving fish. The shrimp love low 70's/upper 60's temp.

i BET the bettas LOVE bowl with shrimp *burp*



how new or old is this tank?

Any medications used in the tank (any meds with copper in it is bad)? Just asking since you kept fish previously in there.

The betta's not there anymore...
and as shrimp zoo said, if you've use medication previously it is very possible that the wood soaked up some.

It seems like some kind of a metal contaminant to me. Try adding some Kordon Rid-Metals water conditioner and then do another big water change. I've used this stuff successfully after dealing with a bout of copper contamination.

If its not just this tank, and the shrimp keel over in the bowl as well, you might have some contaminant in your tap water.

I'm sorry the betta ate its own fins?

That doesn't happen. If there are bacterial infections or other fungal issues in a tank, it'll quickly kill off a colony.

Did you acclimate your shrimp to your tank before putting them in?

Not true, bettas can quickly become fin chewers. It's like a bad habit really caused by nervousness on some, just habit with others. Common in the halfmoons I believe but don't quote me on that. I have a girlfriend who has a fin chewer...she's moved him to different tanks trying to make him happy but he just keeps doing it.

I would strongly suspect a metal contaminant as well.. either residual from medication or from your tap water.

Cherry shrimp are fairly hardy and should be lasting longer than 24 hours unless there is something toxic to them in the water.

they are cherry... all my tanks are same temp/parms ... i actually use the big tank to "seed" (not the right word) the smaller tanks on water changes and keep them cycled


so.. that translates to .. umm ... no

but i do move the shrimp around normally no problem

yes, he's a pissy little fin chewer... if i don't pay attention to him he chomps his fins... it's his way of 'getting even' and getting attention....

this time he went nuts cause i was busy for a few days...

i also think it's because he's all fin and i had a filter so he felt like kite in the wind.

i am SOOOO careful with meds, HOWEVER ... i did treat this tank for planera 3 months ago (no shrimp in it at the time - or snails)

AND

i did have my furnace bled and it caused air in my line - i ran the water for like 40 minutes before i used it anywhere in the house

I NEVER THOUGHT OF THE WOOD HOLDING THE MEDS/CONTAMINANT.

should i pull the wood out - i have been thinking of it as it's just regular driftwood. it was the only thing i could find that was around 2.5x 2.5 and i needed something small.

i put an 'extra' endlers livebearer (they keep having babies!!!!) in there to see if it only effects shrimp.

...

luckily i put in my culls (okay so some weren't culls, but most were)

...

so do i pull the wood?
