Gotcha, if you want him to grow faster you could have the temp slightly warmer too. Warm temp=higher metabolism=faster growth, but a possibly shorter life. That's up to youI chose Beefheart because it apparently boosts fish growth.
I've fed mine black or blood worms every other day, they really do grow slowly at first. Also that's exactly why I prefer worms, less fat, smaller portionsI also heard that it should not be fed every other day/daily because of the high protein and fat that will deteriorate the Bichir's health over time.
Alright maybe that will just be a once a month treat, I feed my bichir brine shrimp but it takes him forever to find barely any so is it a good idea to just go with full raw shrimp? I also feed Tilapia and Hikari Carnivore.
I usually take the tails off the raw shrimp and its perfectly safe I actually learned it from the king of DIY on YouTube. I feed my large south American cichlids raw shrimp maybe once a month as a treat and frozen blood worms maybe once a week. I mainly feed different types of pellets and vegetables for my omnivores.
