I havnt tested the water and havnt for years, its always seemed ok, the tank (4 foot) is well established running a good sump and a decent canister, not overstocked at all, possibly under if anything, the clown loaches are happy as is the other inhabitants, (angels, convict, JD), i would assume the cichlids would be the more robust of the two.
Just got a load of live daphnia today, he is chowing down on that
Will look out for the frozen mysis shrimp and see if i can find any.
The more reading i do on the net, the more it crops up that they are often picky. I guess ill just have to keep mixing it up, im sure everyone will benifit from added variety in the diet.
Thanks for the help.
Duncan.
