When did you get these cichlids? Do you have pics of all your cichlids? Ibr3ak is correct in telling you that excessive proteins brought about by meaty foods particularly bloodworms can cause digestive problems to vegetarians particularly bloat. If you must find commercial foods for them, then pick brands with protein content no more than 32%. It matters if you are not prepared to deal with bloat and other digestive issues.
I see you relied on Mardel test strips to test your water. For accurate results, try the API liquid test kit and compare the differences. It has always been common knowledge that test strips are totally unreliable.
I've had the cichlids for about a month now. In the beginning they ate the flakes, but eventually ended up spitting them out and now they won't touch them. So, what do you suggest I feed them if commercial foods aren't ideal? I have a FW liquid test kit, but the LFS said the strips work just as well. I didn't realize test strips were such a fishie faux pas. As for pics, no I don't have any at the moment. I have a bright peachy orange one (orange zebra), a light blue one with faint vertical blue stripes (blue zebra), 2 that look like the firemouth cichlids (which aren't African at all) their top fins have the red and blue stripes on them, a small cream colored one that's starting to get horizontal grey stripes (pindani ?) and one that reminds me of a blue gill or a sunfish. I'll try to post pics tomorrow. Thanks again everyone!!
