Generally I would say yes Kamfa could be somewhat slower growing then ZZ but not always. Though It would depend on the exact genetic makeup and it is not always as simple as Kamfa or ZZ as there are degrees to the proportions of exact blood of each species that the hybrid makes up depending on the lineage of the specific FH and generation of lineage. Yours appears to be a later generation Kamfa as a 1st gen Kamfa to my recollection is a ZZ Flowerhorn x vieja blood. Then each generation after that is just crossing back to the ZZ and gradually thinning out the vieja blood whilst inbreeding the genes and refining the bloodline.
F1=ZZ x 50-100% vieja blood
F2=F1 25-50% vieja blood x ZZ
F3=F2 12.5-25% vieja blood x ZZ
F4= F3 6.25-12.5% vieja blood x ZZ
And so on and so forth…
A little bit of vieja blood can go a long way as it has high influence on the hybrid. I would guess yours could be an F3 or F4 Kamfa possibly but indeed it is a Kamfa even though it almost resembles an SRD. But likely being a later gen Kamfa and actually being mostly ZZ genetically explains that away.
Short answer: Yes, No, Maybe so.
I will ask though.
Tank size?
Tank temp?
WC schedule?
Feeding?
Also probably has something to do with it being short-body. It won’t get quite as big anyways.
