Thanks for such an informative reply. I have him in the hopt. tank with the diamox and actually was able to get a small syringe from the vet’s office which I had to go to today and injected some ocean rider red shrimp with some of the diamox. I saw him eat one and he was looking at another but I had to get busy with other things. I’ll count the remaining ones I put in there later and see how he did. We had bought red shrimp about two years ago and leave them downstairs for emergencies. It’s times like these I’m glad we did. I tried injected the frozen PE mysis too. They looked like they plumped a little so I think it took some of the Diomox. I guess every little bit helps. Thanks again and I hope this helps him. He’s one we raised – third generation fry from our original pair. Thanks again.
