Mijn vis had ineens ook zoiets. Ineens zag ik een witte puist, ik heb hem meteen apart gezet, omdat het besmettelijk zou kunnen zijn. Ik had ooit een site gevonden (en bij favorieten gezet) met allerlei enge visaandoeningen (Engels). Maar nadat ik mijn laatste bij de vriend van LittleAnn heb gebracht, heb ik die eruit gegooid 
Bij mijn vis viel dat witte ding er ook vrij snel af en ontstond er inderdaad een gat. Ik heb er speciaal spul bij gedaan, maar de volgende ochtend was ie al dood... 
Denk dat het een schimmel is geweest.

Body Fungus (aka Mouth Fungus, Columnaris)
Symptoms: Tufts of grey, white, or grey-white material around the mouth region, white or grey patches on the fish's skin
When you suspect a fungus, there are several possible causes. All are somewhat similar in appearance, and include common Fungus, Mouth Fungus, and Body Fungus.
Body Fungus and Mouth Fungus are, in fact, the same affliction, both caused by the Chondrococcus columnaris slime bacteria. The affliction can attack different parts of the body, and thus is sometimes thought of as two separate diseases, although they are the same.
Mouth Fungus isn't a fungus at all, but a kind of bacterial infection. The slime bacteria string together as very fine 'threads' to form the white, tufty appearance.
remedy:
The first thing to do is to contact your vet or petstore for further instruction. Several good medications are available. If the problem persists, your vet or petshop may suggest antibiotics. It is wise to treat your main tank in order to ensure that you have successfully removed all traces of the bacteria from it (although it may be beneficial to also move a badly afflicted fish to a quarantine tank). Avoid using a net to catch an afflicted fish... use a plastic bag or other suitable container. Leave the filter running, but remove any activated carbon because this may take medicine out of the water. Remember, the key to effective treatment is prompt action.
