Thanks again for the response.
We threw out the Cycle stuff as soon as we read your post. We're going to go out this weekend and find some of the other things that you mentioned.
We returned the dead tetras and purchased 5 Zebra danios. The guy wasn't too keen on selling them to us. He said that the really only reason why people get these to cycle their tank is because they're cheep. He wanted us to buy some Platies that were pretty expensive for starter fish (I know that that's his job though).
My question is...should I leave Betta Bertha in the tank with the new Danios (she just seems annoyed at them like she's wondering if they'll ever stop moving). They swim by each other with no problems so far but she's been hiding in a rock thing a lot or along the bottom (they've only been together for like 20 mins though). Should I leave her in there and see if she survives or take her out and put her in the smaller betta tank that I have? Would a smaller tank not go though the same cycle in theory? I want to give her the best chance possible but understand the risks to her.
Sorry I have to many questions but you all are just so helpful to me! And I really appreciate it!!
