Help with diagnoses

Hi All,

350L tank that has been running for 3- weeks (after fish/water/substrate/plants etc) were transferred from a smaller tank that had been setup for over 6months.

Ammonia = 0, Nitrates = 0, Ph settled at 7. Temp 27.5

The issue is the behaviour of some pearl danios and penguin fish.

Some (not all) frequently scrape/rub themselves against plants while swimming.

I've read that this can be due to chlorine in the water or parasites. There are no visible parasites on the fish and they are as active as always (very!) and still hungry come feeding time.

If it is parasites what treatment would be suitable? I'm a bit puzzled as I thought such an illness would have a bit more impact on the fish and perhaps spread?

any help would be great! :D

Have you added anything new to the tank, fish, plants etc?

Could be the start of itch. To save bombing with medicine. Try increasing the tank temp to 29-30 degrees. Make sure you have plenty of airation. See if they stop doing this after a 3 days. At this stage do a water change, using a gravel vac.

Keep an eye out for spots. If other species or more fish scratch regularly, you may have to treat. If no signs of spots, probably flukes, not visible to eye.

Frenchy :D
