Congrats. Mrs. Southern .
You got me laughing just imagining you in your bipolar moments of joy and pain mixed all together
.
You can safely leave them without feeding for a day or two , to give them time to adjust to the new environment and new water parameters .
Leave the lights dimmed for awhile and do your water testing straigh tap prior and before 24 hour aging (With an airstone or surface agitation in the aging bucket ) .
Until then if you do your WC , start with 30 -40% WC and observe their reaction to it .
Good luck and congrats. on your happy moments, receiving your first batch of discus fish
. Those are some unforgettable moments , that's for sure .
