Okay cool. The multi vitamin is once every two weeks and only on like 6-7 crickets. If you put it on the entire 50-60 youre going to have an issue. She may lunge, with a veiled its quite normal, theyre firey. I'd still use tongs to feed them or use a large clear cup so she can see inside. If you got the reptisun 5.0 from the pet store im assuming its the t8 since petco and petsmart only sell the t5s in a few locations and not across the board. If it is the t8 you'll want to replace that with a t5, reptisun or Arcadia 6%, arcadias the recommendation. t8s dont alway output enough uvb at the distances our chams are in a wide enough area. If it is the t5 the issue is supplementation, which will be solved if you follow the regiment of 6-8 every other day dusting with just calcium every day and a vitamin (i use earth pro A) every two weeks. If you have a t5 the calcium with d3 is overkill, but your petstore will tell you the cham will die if you dont have it, theyre dumb dont listen to them lol.
