one of my fish has gone down with what I thought was saprolegnia around her mouth after jumping across a divider to join the angels ( and presumably being attacked ), but the stuff has now spread to her dorsum so I'm thinking probably columnaris now. Three days in a hospital tank with salt, and daily 30 min baths in 1L of saline with 1 drop of 1% methylene blue has not halted the progression. I've also been swabbing her mouth with undiluted 1% mb.

I'd like to get some of this fluffy stuff and examine it under a microscope so I can find out what I'm dealing with.

Anyone know where to purchase second hand microscopes?

Good point. Listing 483267010 also looks promising. Is that an oil immersion lens attached?

sorry not up with the play

i just use an older style but powerful one

The one in the pic looks like it could be but you'd actually have to know the power of the lens to confirm.

Doesn't look like the seller knows what they're selling. But I'm thinking it might be a water immersion lens.

Got a microscope off TM.

Now where does one buy slides, cover slips and dyes? Only can find internet sites .. no bricks and mortar shops.
