did not know you had installed a Uv peter, how long you had it, where did you get it from and waht price.

I been thinking of one for my new set up...

hope you get those spiders identified, always nasty when you find some thing in the aquarium that should not be there..

my uv is built into my external filter but they do sell the ones that connect to your filter pipes .... http://www.allpondsolutions.co.uk/aquarium-filters/aquarium-uv-sterilizers.html

or external with 9w uv http://www.allpondsolutions.co.uk/aquarium-filters/aquarium-external-filters.html

but ive had it since i got discus few months back

yh i hope i do aswel .. there so tiny hardly noticeable unless looking for them .... but just have to see how it goes but due to move soon so ill be shutting down those tanks and giving them one hell of a clean before setting them up again

Long shot, but are they anything like this,

I would dose your tank with some aquilbrium salt, you can use it with other meds, it is a natural antiseptic so should help the sores.
I use it in my tanks all the time, at a dose of 0.1% ( 1 g for each litre of water) I've not had any issues since I've been doing it.

Although the BNs are freshwater fish the low dose/percentage won't hurt them at all.

Cheers Jon

no they are literaly a dot with tiny legs all the way around the body ... way to small to capture on any camera but ill get on paint later to try and draw out what they look like

Good Day -

Peter - your tank is a well Planted, I was wondering if you were dosing any fertilizers/neutrients to the tank or do u have any fertilized soil in the tank , Excess dosing of nutrients can also be the case since this is affecting the skin of the pelco. Just a suggestion . do keep us posted .

no most of infected died unfortunatly but no just used aquarium sand very fine ... no fertilizer of any kind atal no co2 ... nothing just aquasafe and thats it
