I have 10 Zebra Danios in my 60 gallon. I just realized that two or three of them are acting weird and have white patches on their bodies. What do I do? Should I take them out? How do I treat them? Or will they heal by themselves? Are my other fish infected too? Its urgent! Help please? EDIT: I panicked and seperared the two danios who were acting weird and have white patches. The thing is, I originally had 6 danios. Yesterday, I bought 4 more. I couldnt quarantine them since my dad threw away my small quarantine tank yesterday morning (how convinient. Thanks dad). Should I try to figure out who the new ones are and quarantine them along with the fungus ones? The new ones are very small and pale (stress?). The ones I have had for a while now are large and have vibrant colors and amazing fins. I take it they are healthy. Can they easily fall prey to the fungus though? If it even is fungus... I quarantined the two in a small tupperware (its all I had).
