Fish Fanatic
OK I have a major problem and in another way I don't...
I got some more fish from my LFS about 2 weeks ago and put them in the quarintine tank as always - I'd previously had 3 neons in there from last time as I wanted them to grow a bit bigger before I put them in my community tank (I have 3 silver sharks in there & I know from past experiences that baby neons make a tasty snack), they'd had whitespot but it'd cleared up and they'd been fine for about 6weeks till I introduced the new fish - 6 more neons (I wanted a shoal) and a baby south american plec.
Since then ALL the fish got whitespot inc the 3 bigger neons so I did as usual - upped the temperature & added King British Whitespot Terminator to the tank but it didn't seem to work. The whitespot got worse, so much so that one neon was literally covered in it
It was past the 7day return policy to take them back to the shop so I persevered anyway but over the last 4 days all my neons are dead and only the catfish/plec is still alive in the tank. I've cleaned it and done patial water changes etc but I'm really worried now that my plecs gonna cop it as well(!)
I did my usual tests on the tank and the stats are PH - 7.2, Ammonia - 0ppm, Nitrite - 0ppm, Nitrate - 5ppm
Can anybody give me an idea of whats wrong in my tank and advice on the plec?
I forgot to mention when I added the new neons and the plec to the quarintine tank that I'd also bought 3 plastic plants and put them in at the same time, I rinsed them in declorinated water first but could that have done anything???
