Ok thanks guys I figured this was the reason the little one couldn't climb, and the dust on the sides does make sense.
As for the crickets the one pet store is crap and said no, before they even put it in the tank to sell they coat them in a bag and shake them, they wouldn't let me put a few aside before they coated them either for me. But I got another pet store to make a deal with me that every Wednesday when their shipment comes in they will put 20 aside for me without the coating and I will just come get them, and I will feed them my own foods. I am looking into actually breeding my own crickets when I get more T's lol.
Good deal! I'd be a dedicated shopper at the 2nd pet store just for that and I would cease all business with the first pet store, mention that treatment to your friends and family, and write them a bad review. I can't stand businesses that flat refuse to help a customer with no reason.
As for food Flukers orange cubes along with Flukers high calcium cricket dry feed ($20 for both on amazon and the calcium feed is a 6 lb jar) is what i use for both crickets and roaches. The orange cubes provide hydration along with vitamins/minerals to compliment the calcium dry food.
The instructions say to use that to gut feed the crickets to give your animals the highest nutrition. Also says to stop feeding the crickets the day before you feed them to your pets. I keep forgetting to do this but i don't think it will matter any to the spiders eating them will it? they'll just dissolve the undigested oats or whatever along with the cricket or roach guts i'm guessing.
