You are so welcome! I'm glad to help.
Look in the frozen food section and find english peas. Usually there will be smallish packages, maybe 12 oz or so. The frozen ones are better and need to have the skin off and be slightly mushy from the microwave.
You could also get some garlic, either the whole cloves and chop them yourself or the jars of minced garlic (I get that) that they usually have sitting on an end cap in the produce section near the onions and potatoes.
If you nuke an english pea and rub garlic on it, or put some garlic juice from the jar on it, it will be very tempting to your Patootie. Fish love garlic and it is very appetizing to them.
Ask someone at the grocery store for the frozen english peas. I know sometimes I'm searching for something and look right past it until someone points it out. I don't think the canned sallted pea you have tried will hurt him, but I think it's better not to have salted peas for him.
Keep up the good water change schedule. I know you can't test it confidently without your test kit, yet, but assume that his water needs to be changed very frequently.
Until his tank is cycled and has all the beneficial bacteria needed to handle harmful byproducts, and you have the liquid test kit to keep a watchful eye on the parameters, I would do water changes every day, at least 50%, as Lupin suggested.
Pristine water is of utmost importance to his health, especially since he seems to be a little off in his behaviour and this may indicate he's not feeling his best right now.
Ah, I will ask for English peas and get some garlic. The ones I had were frozen as well, but like you said, I think he needs ones that don't have salt. His belly looks a little bloated and -excuse me- his poo is a dark greenish black color, so I'm definitely going to Wal-Mart in the morning. -The joy of living half a mile from Wal-Mart.-
I'm a little scared of changing the water everyday. Patootie is always freaked out after the change. And it can't be the water, because I now know how to get the temperature the same and the water has been treated with the dechlorinator. Anyways, I will try me best to do it daily.
