seems like that could be a form of bacteria or parasite because of the quick onset. Is the medication that you are giving them working now? If not I would try coppersafe from mardel. That works very well. Just make sure that there are only fish in the tank if you but it in. Very good med.

could be costiasis here is a link HTH

Could it be as simple as CO2 poisoning. 86f is kinda hot for a tropical tank and with the water that warm you need extra aeration to keep up the proper levels of disolved oxygen.

Could also be protozoan infection, I have used the Protozin on Magic, my Plec who suffers an immune disorder and is prone to these things. It also helps to keep your gravel completely clean, hoover it regularily and use an external canister filter. As it all seems to be bottom-dwelling fish you're having the problems with, I would strongly suspect thats where your issues are.

Esha also make an anti whitespot (will also treat protozoan parasites and costiasis) and an anti bacterial remedy (in case of bacterial bloom in the gravel) which can be used together. Magic was also once prone to dropsy-like symptoms and I used these medications. Might be worth giving Eshas anti-whitespot treatment a go if you see no improvement with protozin but make sure to remove the protozin with a water change and carbon before using the Esha medication. Good luck!

I thought loaches like water kinda cooler. I think that looks like a fungus to me. If in fact that is what it is the temp. Should be a lot lower I think it spreads more in warmer temps. Some one please correct me if I'm wrong. But I dony think I am.

i haver had the tank at this temp for 2 yrs now and my loaches have been fine i read in books and stuff that the temp for loaches can from 23-30(73-86) so i think it maybee a matter of preference i fuond that at lower tepm they were suceptalle to ich but had no problems since raising the temp till now fish at a higher temp grow quicker to in my personal opinion i maybee wrong but all the fish i have tollerate the high temp i only buy fish that can the treatment i am using seems to be working also found out my ammonia levels where off the scale so addressed that problem too thanks all
