For enhancing color best is shrimp diet and krill. Depends if your Flowerhorn has red it will pop.
New spectrum is good I use hikari gold sinking pellets.
Just be careful with a shrimp/krill diet. Krill and other shrimp seem to be the go to answer for color enhancing questions but I believe krill's use is actually more harmful than beneficial in this instance, at least IMO.
Krill contain astaxanthin, a keto-carotenoid, which is what causes fish to turn red. Salmon eat krill and other shrimp high in astaxanthin and in turn the salmon develop red meat. However, salmon are adapted to eating shrimp and krill all of the time. Flowerhorn and other cichlids rarely eat shrimp, especially shrimp high in astaxanthin. So when we feed our fish krill (a marine shrimp not a cichlid's natural prey) our flowerhorn take in the astaxanthin and becomes more red as the astaxanthin is worked out of the body. It is a temporary effect. Once the astaxanthin is out of the fish, the fish may turn dark and loose its abundance of red, even sometimes its kok.
A cichlid fed mostly on krill and shrimp will eventually develop white poop and may even die if their diet is not corrected. Krill, and other shrimp, should not be used as a staple for color enhancing but as a treat outside of their normal staple food.
Just my 2-cents![]()
I feed my flowerhorns once a week brine shrimp or krill. It's not on a daily basis but brings out their reds like crazy.
Flowerhorn are never in the wild so can't really say what they eat. They're tons of pellets higher quality ones that have shrimp meal and krill meal already incorporated in their diet.
I like your point of view though but from experience I never had an issue
I agree with nearly everything you said and experience is the best teacher, however, "Flowerhorn are never in the wild so can't really say what they eat"...really? They are just Trimac cihlids bred with other central american cichlid, none of which have access to krill or other marine shrimp.
Pellets do have shrimp in them but in small amounts. They also have squid, mussels, beefheart, flour, garlic etc, etc in them too. What I was getting at before is that feeding SOLELY or mostly shrimp will have side affects that out weigh the pros of use. It's the astaxanthin levels that I am primarily warning against not the variety or types of food.
Trust me, I got this info from experience too.
