Sorry for asking so any questions all the time, but.....
this week I have lost 2 fish, one Tuesday & one Thursday, I haven't notice any change in there actions they have been eating fine, swimming fine, I haven't notice anything wrong. Each one that has died was stuck to the side of the intake cover on the filter. I use (2) Aqua-Tech 30-60 Power Filter w/bio-fiber biological. This may be a silly question but could the fish get sucked to the side of the intake & not be able to free themself? I don't know how old they could have been but I brought them January 29th,
but that would be odd 2 dying in the same week.
I have a 55 gallon tank with:
(4) Rosy Barbs, (3) Bloodfin Tetras, (6) Misc. Planties, (4) Dalmation Mollies, I had 1-Dalmation to die & 1-of the Misc Planties to die.
Also in the tank I have:
A sunken ship, silk plants & (2) real Java Plants.
Last Thursday, I did a 20-25% W/C, so on Sunday I did a testing using the API Test Kit the reading was:
Ph 7.6...High Range Ph 7.4.....Ammonia 0....Nitrite 0....Nitrate 5.0, did a reading on Tuesday, everything was the same, Thursday (last night) did a testing the reading was: Ph 7.6...High Range Ph 8.0....Ammonia 0....Nitrite 0.
(?) (why so high), after the reading I did a 20-25% W/C, since the nitrate was so high could this be the reason for the dying fish?
I forgot to menation I have 3 Mystery Snails, but I can only find 2 of them.
My Temp stay's about 78...
My tank has been up & running since about the first of January 2008.
Sorry for the long post, I was trying to get everything in.
