Sick blue oranda & black telescope?

I lost the blue oranda yesterday. He started to struggle after the large water/decor change on Saturday. He seemed to rally a bit during the evening and on/off Sunday morning, but when I returned home in the afternoon, he was gone.

The two babies seem to be doing ok so far. The white patches on the black moor are fading and his coloring seems to be less pale. Hopefully this indicates a positive response to the flubendazole, kanaplex, and salt.
