Hello aquarium community,
I have a 600L (158.5G) community tank (discus, bosemani, scissor tail, harlequins, clown loaches, mollies, gourami, cories, kribensis, and many more). My kribs have been very successful breeders in this tank so I have quite a few, at varying stages of maturity. Over the last couple of months, the mature ones are dying of something that only seems to affect them. (I lose one or more a week.)
At first, it looked like a fungus, as growth could be seen on a few, but this was not the case for all of them. Common symptoms include heavier breathing and inability to close mouths, followed by swelling of one or both eyes.
The tank gets weekly water changes (but not as regular gravel siphoning.) I can certainly increase water changes, but this seems like something more than mere water quality, since none of the other breeds are showing signs of sickness.
I'm now trying to catch those with any early signs and place in their own tank, but I'm unsure of how to treat once there. I have my only two albinos in a floating bucket with methylene blue--because of possible fungus. In the photos you can see one albino with very early signs (not closing mouth much), and an albino much further along with two swollen eyes (dark spots are blue dye from treatment). The last picture is most recent krib to be euthanised in clove oil.
Any advice would be gratefully received as the kribs are some of my very favourite swimmers!! Thanks! Tena koutou ... Rhoda
NOTE: I've read some forums here that name products I cannot get, as I'm in New Zealand (and your regional groups seem to be North American and eastward--not westward or South Pacific.)

I have remarkably little between-breed aggression. The randy male Mollies annoy the discus, and the still-youthful but large kissing gourami also annoy the discus with their incessant sucking for slime. The bosemani play together and never bother anyone.
