I bought a welso about a week ago. It ate well the second night. Then on the fourth night I fed it but had to keep my Sailfin and Lamarack Angel away as it took awhile to open all the way and take the shrimp portion that I gave it. Now it does not look like it is opening. It looks like it is shrunk to the skeletal frame with pail coloration. I checked and re-checked my water parameters and everything is good. My Alk was a little high but everything else is good. I even finally got my PH and PO4 to at desired parameters. What else can it be? If anyone knows please let me know?:angryfire:
