When I was restocking my Malawi Hap food supply with Dainichi foods I was told by Dainichi sales that it (XL Pro) was a new formula specifically designed for large cichlids such as Malawi haplochomines, Frontosa/Gibberosa, and New World Cichlids I decided to try it. Upon receiving it in the mail and taking a sniff (Dainichi food seems to have a strong smell that isn't exactly appetizing to us humans but does have a decent smell for a pelleted fish food...ie I can smell the ingredients) I decided to feed it to the fish to see how they liked it. They voraciously attacked the pellets splashing water into puddles on my wood floor trying to get the food.
Here's the results. While I do feed frozen krill/mysis shrimp usually once every other week or so, XL Pro was the staple food the past few months. XL Pro has a high krill content too, so I can't say all the results were just because I fed frozen food. My what-was-5.5" Exochochromis anagenys male is now 7-8", developed a fully pointed anal fin and clearly has blue on the face, gill plates and upper body half with more on the way. 2 of my juvenile A. stuartgranti Maulana & Ungi peacocks grew 2" and are fully colored.
I've had nothing but good results with XL Pro.. It's also quite cheap compared to their other formulas.
I highly recommend this food to people keeping Malawi Haplochromines...
