I've been feeding frozen Omega Brine shrimp cubes to my africans for years now maybe twice a month as a treat. and lately I've added Omega frozen krill cubes to the snack list. all the fish seem to really enjoy this stuff.

anyone else using any frozen foods to feed their fish ?

I feed Hikari Bio-Pure bloodworms, and Piscine Energetics freshwater mysis shrimp, to my carnivores. My 60 gallon tank which has the elipsifer eels gets a feeding of frozen food almost every day because the eels won't take any dry foods yet. The other occupants in that tank (tretacephalus, leleupi, calvus, petricola cats, peacock and brichardi) get a light feeding of dry food in addition to the frozen. I don't want them to get totally spoiled and refuse to eat dry food! My angelfish gets a few frozen meals every week, in addition to her dry foods.

I put vitamins on the mysis shrimp before feeding, because as I mentioned earlier, the eels only eat frozen food, and I don't know how balanced a diet that is. I especially like feeding the freshwater mysis because the shrimps are much bigger than the saltwater mysis, so there is more meat, and less mess. I like the Hikari Bio-Pure brand of bloodworms because of their so called 3 step sterilization process. They advertise that their food is bacteria and parasite free. They also put vitamins in their food.

I too use frozen foods for all my carnivores. Frozen blood worms, brine shrimp, mysis and krill. No food on Saturdays after the water changes and usually on Wednesdays I feed flake food. I alternate the foods so they don't get the same 2 days in a row.

Once every week or two I've been giving one cube of the frozen brine shrimp unfused with spirulina to both my tanks.

Should I be doing this only with my haps and not with my Mbuna?

Don, I am probably overly careful when it come to feeding a meaty diet to my herbivores. However, I have always believed that herbivores need a vegetable based diet while carnivores will thrive of a meaty diet.

Now I do not suggest to feed only one particular type of food. You can vary the diet for either of them. There are all kinds of veggie based foods available including the real stuff (zucchini, lettuce, .....) and of course a great variety of meaty foods. There are many choices for all, I just don't think that a carnivore will be very happy with some leaf lettuce.

My apologies to the mbuna fans (used to be one myself many years ago) but mbuna's eat like pigs. No matter what you give them, they will just suck it up. In the lake they live off the sediment covered algae layer called "Aufwuchs" and yes, they will surely eat the occasional crustacean that is hiding in that algae cover too. Yet 95% of the food intake is algae.

I do mix some brine shrimp- or seafood flake in the spirulina flake I feed especially to my Tropheus fry and juveniles. Seems to work out fine.

Please don't get me wrong, this is just my way of doing things. I do know of Tropheus keepers that feed their fry nothing else but freshly hatched brine shrimp and they seem to be doing good. It is just my believe that if the fish eat it and don't get sick or die doesn't necessarily mean that it is the right thing to do.
