Hello and welcome to FF! Stella needs to be quarantined in a tank by herself. Just use damp (dechlorinated tap) unprinted paper towels for substrate; a water dish with dechlorinated tap (Seachem Prime or ExoTerra Aquatize) to frog's chin level; and a silk plant to reduce stress. Natural Spring Bottled water is processed to match city standards for human drinking and can be unsafe for frogs.

Got load crickets with lettuce, carrots, and cherios cereal 24-48 hours prior to feeding frogs. Crickets should be same size (or smaller) than distance between frog's eyes. Those Fluker's orange cubes are not good; throw them away. Get either Repashy or RepCal CA/D3 and vitamin products and use per these schedules: http://www.frogforum.net/food-feeder...schedules.html.

Get some unflavored Pedialyte or similar baby electrolyte and Fluker's ReptaBoost. Mix 10% Pedialyte with 90% 80F dechlorinated tap and bath frog (small critter keeper or bowl with holed up top) for 20 minutes (cover with towel to reduce stress and keep heat in) in chin deep solution. Do that in evening after frog wakes up and then try to feed. Dust all crickets for one week in the Reptaboost powder; then you can resume use of CA and vitamins.

Let us know of any changes and if frog get's worse do try to find a herp vet now in case need to take it there. Good luck !
