Hello
Hoping someone can help shed some light on a new tank problem I have had. Let me begin.
I have had a 30 litre cold water biorb for the last 27 months in which i have been keeping 6 white cloud mountain minnows. I never had any problem with this tank apart from 2 of my minnows swimming in the filter which I think is a design problem with this tank. When the second of these minnows did this I decided it was time for a change so I went out and bought a new tank and this is where my problems really began.
I now have a 64 litre bow front tank. My thinking was to transfer my old tank into the new, add a heater and keep a variety of different fish.
I bought my new tank on Tuesday, along with some gravel a couple of new ornaments and some bogwood. I cleaned everything with just cold water and soaked the bogwood. That evening I put the gravel, ornaments and bogwood into the tank. And filled the tank about half full using conditioned tap water (I have always used Tetra Aquasafe) and then added a further 8 litres from my biorb. I set up the filter, set that away and added some interpet filter start. I then left the tank 24 hours until Wednesday evening.
Wednesday evening I took another 8 litres of water from the biorb and topped up with conditioned tap water. I tansfered my two moss balls and a large clump of java moss into the new tank. I also transfered about a dozen small pebbles and three biorb colour balls (which look lovely on black gravel). I measured the water temperature in both tanks and when it was the same I transfered my four remaining minnows. (just before I did this they had fed). Initially I had no concerns as they seemed happy enough checking out their new enviroment.
Thursday morning, the fish seemed to be very withdrawn spending most of the time hiding, this continued thoughout the day and evening. I was a little concerned that one of the minnows did not seem to be swimming normally (seemed very lazy). I put a small amount of food into the tank and although they ate it they did not do it with there usual enthusiasm. I also added a little more filter start as per recommendation on bottle.
Friday morning and no change in the behaviour of the minnows, Friday evening when I got home from work one of the minnows was at the bottom of the tank dead. I tested the water and even though I could not see any problems with the readings I did a 50% water change anyway. I did not feed the fish today.
Today (Saturday) I have got in from work to see my remaining minnows have gone to fishy heaven. Again I have performed a water test and found no unusual readings.
The water test results were the same on both Friday and Saturday.
Ammonia 0
CL2 0
PH 6.8
KH 6
Gh 4
NO2 0
NO3 0
These results are in line with I used to get with my old biorb tank. I am a little perplexed by what has happened and simply do not understand it. Any help and guidance from here would be greatly appreciated. The really annoying thing here is that I bought a new tank so the minnows would not get eaten by the biorb filter, 4 days later they are all dead.
