Hi quality frozen mysis, krill and plankton are good. I avoid blood worms, beef heart, and brine shrimp. Is it good for them? Many hobbyists believe that their particular combination of foods is exactly the right one, and many have great luck feeding NLS only. The only across the board rule that holds true for all the fish is to not overfeed them. Otherwise, common sense says that varied diet of high quality foods can't hurt.

Now, I have seen instances where fasting for a few days followed by high quality frozen treats will trigger spawning behavior in some Tang cichlids...

 

thanks for the advice. I am only going to feed frozen once a week and the rest of the time they will get the other stuff heavy on the greens.

 

I feed NLS Thera+A every day. They get the occasional O.S.I Spirulina flake Dainichi veggie fx and homemade shrimp mix on the weekends.
P.E mysis shrimp is a good treat to get them to spawn.

 

Thanks for the advice. I got a the colony from two different and reliable sources and now I have lost three of them. All the smaller ones from the guy who I have always gotten great fish from before. The rest look great except for the last smallest one. The stomach is sunken slightly. I am afraid there may be and internal parasite. They are all eating great and I am not real anxious to medicate a 220 gallon tank. Has anyone had any luck with medicated foods?

 

I always use medicated food for illness, but I soak NLS with the same quantity of metronidazole as I would use for the tank size anyway so no savings there.

 

Agree with DJRansome. I would treat with metro soaked food, using 1/4 tsp per 40 gal. I have also had good success using jungle parasite clear in my 210g tank.
It coulod also be a matter of aggression in the tank. I have only ever lost Nasutas to illness caused by aggression.
