Just a word of caution on the Bacter AE... the spoon it comes with is considered over-dosing to most people who use it... and if a tank doesn't have enough aeration, can cause shrimp deaths. Many people I see who use this product tend to under-dose it to prevent deaths although one person had to completely stop using it entirely.
You may want to try and stick with an algae/vegetable based diet (great idea with the kale!) and add in protein occasionally... which may come in the form of fish food? (since it is a mixed tank...)
