High Pressure (Cold Front)

[gatorsean]

I have had a few issues with disease in my tank but now everything seems like its starting to get under control, but for the last few days my curviceps (3 of them) have been acting very lethargic, holding their fins close to their body, and not/barely eating. Do you think this has to do with the fact that florida was just hit by a high pressure weather system? I now a lot of game fish in florida do this but not totally sure about tropicals.

Might be something other then that, try filling out this form to help-

Tank size:
pH:
ammonia:
nitrite:
nitrate:
tank temp:
did you cycle your filter, if so, how?

its a 55 gallon. the ph 6.9, ammonia 0, nitrite 0, nitrate 0. The tank is moderately planted but i also cycled the tank but that was about three months ago so i dont think ammonia poisoning is the problem. also the other fish in tank, celebes reainbows, pristella tetras, otos, are doing just fine.

nitrate shouldn't be 0

nitrate shouldn't be 0

What a find..... Lol

Actually it is not uncommon in planted tanks, especially when the plants are plentiful and/or the fish load is smaller, for there to be 0 nitrates. Between the lowered ammonia levels due to plants eating it which ergo means fewer nitrites and thus lower nitrates (which the plants also eat). there is 0 left to be measured. Hi tech planted tank folks routinely add nitrate to their tanks, I know I do.

well im pretty sure water chemistry is not the problem. i suspect some kind of parasite or ich. ive been treating for ich for 3 days with ich attack now but my curviceps havent shown any signs of improvement. they still are very lethargic and either shimmy in place or scratch on the plants and rocks when they move around.
however i asked the question about barometric pressure because they acted this way a few weeks ago when a cold front came through. also none of the other fish in tank so any signs of discomfort.

tropicals aren't quite as sensitive to high and low pressure fronts as subtropicals. The subtropicals use them for spawning triggers, or as a signal for yearly seasonal changes. A lot of tropicals will spawn year round, or they wait for the rainy season or similar, so they are triggered by changes in water chemistry, or temperature, or even water level. I won't say that it is impossible that it isn't the cause, but I'd sure investigate many other possibilities first.
