Thanks Guys ! I think they have a better diet than I do actually

I feed them the frozen bloodworms or frozen brine shrimp about every 3rd/4th dy, is that enough or should I make it every 2nd dy?
I usually do 3 smaller p.w.changes a week if I have time so tank conditions don't fluctuate too much & syphon gravel once a wk. & I have 2 filters on my tanks (maybe overkill on my part ha!ha!)
I'm not sure if the PH is ideal for ram fry though! my PH is always approx. 7.4-7.6, I don't use any PH adjusters (I used to but it caused too much stress to my fish). Do you think this PH is conducive to raising the fry if any?
