Anyone know why? (pic)

Anyone know why this set of zoos is doing this. My water temp changed by about 3 degrees over the last few days because summer heat is approaching fast. Other than that Im not sure what might be wrong.
Will they be ok?

- Should I give them a lugols dip?

When did you get them? A dip wouldn't hurt. But zoos are very hardy, i'd just give it some time.
