Lost all my fish

Postby istanley24 » Thu Sep 13, 2012 2:50 pm

At the weekend, we noticed that our bristlenose plecs had a load of babies, we noticed them mostly at night when they would come out onto the glass and they were tiny, so only just hatched. Then it all started to go wrong on Monday. We have lost all of our fish in 2 days (7 cardinal tetra's first, then our 4 platys and 4 guppies and then our 4 bristlenoses and 6 glowlight tetra's). Obviously the baby bristlenose's didn't stand a chance.

Our tank is 150L, and I have kept up with my weekly 20 - 30% water change and tested the water regulary, 0 amonia, 0 nitrite and 40 nitrate (this is what it is out of the tap also), PH is 7.6 and have been using Seacham Prime to dechlorinate the water before adding it to the tank. We have a canister filter and I clean the media in tank water about once a month so that nothing gets clogged up.

I think the cause of this is Ick. The first few fish to die did not have white spots on them, or not that we could notice anyway, but 2 or 3 of the later ones did have white spots on their fins. The last thing I added to the tank were the 4 platys from our local fish shop. This was around 2 weeks ago. Could the fish that were added have been infected?

I am so gutted. We took things nice a slow, cycled the tank for months to get it right and then added the fish slowly over several months, we did everything that I could think of to do it right. And now we have lost all of our fish.

What do i need to do now to make the tank safe for fish to be introduced again?

This is why many suggest a quarantine tank and not introduce fish directly into the main aquarium.
It is possible the new fish got stressed, which triggered the ich, which then spread. I am surprised you lost everything so fast though. Usually you have time to note the infection then treat it before it gets out of hand.
If you have no fish in the tank, keep it that way for at least 2 weeks before adding more. The ich need an intermediate host (ie fish) and die without it.
You will have to either keep adding a small pinch of food daily to feed the filter bacteria, or clean the filter out then start again from scratch.

Keep the tank empty for a few weeks and drop some food in now and then to keep the filter ticking over as posted above. Ich cannot survive without a fish host. The only problem you will face is restocking because the new fish may be carriers. Either treat the fish with medication straight away as if they had whitespot or quarantine them in a small quarantine tank. If you choose to treat them keep the water level low so you have a smaller volume to treat, keep the dosage lower, and give your fish the best chance.
