[fishtycoon]

Hi Guys, i got a bigshock earlier, my entire lot of fish were " sitting on the bottom of the tank and i dont know why?? it is prety much a grow out tank with the exception of two acaras and they were all down the bottom,, approx 15 fish,,, 65 uk gallon tank,,tetratec filter,, feed them hikari gold mini, spirilina, bloodworm,,, everything ws normal earlier today all fish swimming normally,, then went into the room and seen that,,,,

They all seemed to be at the point of death,,but when i netted them out into another tank they felt as though they had plenty of fight.....ALL i fine almost instantly in the other tank now......

With the exception of the acaras!!! the rest are babies of about two inches,,so its not a stocking issue,, i did think Oxygen but ruled that out!!,, good filter thats on it,, tetratec 1200 with really good surface movement from the spraybar,,,,,

What are your ammonia/nitrites/nitrates? You can't begin to figure out what's wrong until you test for those.

amm,,0,,,,nitrite,,0,,,,nitrate,,,15ppm, i thought of swimbladder as i read they can sit on the bottom aswell as the normal floating at top,,but they went back to normal once in other tank (so not swimbladder) lol

Is it possible you have any stray current in the tank? Electrical not water.
