I have a degree in Business Management, which makes me absolutely worthless
in this dialogue. I do, however, have Mbuna. I feed these a variety of foods including algae wafers, plankton, blood worms, flakes etc. I've never had any troubles and my fish are looking and acting VERY healthy. -- Craig Brye University of Phoenix Online "Cichlidiot" wrote in message ...

I still must stick with what I said, though.....In an algae only food to eat scenario, they would probably out compete the other fish....I imagine that's what drove their special qualities.....but they will eat what they can get regardless....As do most critters...some foods are preferred over others.... I do not believe its a fact that a Mbuna cannot digest anything but algae....I am not even aware of another herbivore that is so limited, but I am aware of many carnivores that would do poorly eating grass and brush.

(And before you ask the same of me, mine is on the wall behind me right now). You obviously have never taken a physiology or morphology course. Otherwise you'd know about things like digestive enzymes and intestinal tracts that affect what a creature is able to eat. Here's a very simple example for you: lactose intolerance in humans. This is primarily due to the lack of the digestive enzyme lactase (although in some it is actually a true allergy to lactose or a reaction to other components in cow-derived dairy products). This lack of lactase causes intestinal discomfort, gas and bloating because the lactose cannot be digested. If a creature does not have the digestive enzymes to break down a complex structure (which proteins are BTW) into its more simple components (such as simple sugars or amino acids), then it will have issues eating something which contains a high quantity of that complex structure. Everything I've read about mbuna suggests that they do not have the capacity (ie the digestive enzymes and so on) to live on a diet consisting of mostly carnivorous foods without some serious digestive side-effects, such as bloat. The occasional intake may be tolerated, but not a constant diet of such food. Oh, and for not believing other herbivores are so limited, there are other fish with similar algae eating habits. Several scientific studies are underway with just the primary goal of gaining even more insight into the physiology of the digestive tracts of fish that are herbivores. For example, read this faculty page for a professor at Fullerton: http://stromboli.fullerton.edu/mhorn.html It is of course brief, but shows that there are other fish that are similarly algae eating herbivores. In the case of that professor, his research focuses on several marine herbivores. That is also just one example that popped up on a Google search for research in this field. Now, in the future, if you wish to make such claims, please do not base it on "personal belief". Provide some sound scientific research to back it up. Right now, most of the scientific knowledge indicate that algae eating mbuna should be fed an herbivorous diet. Perhaps you have done an experiment or two comparing the effects of a carnivorous diet vs a herbivorous diet on these mbuna fishes that you'd care to share? |

Don't change a thing then! In my experience, if it ain't broke, don't fix
it! I've had much the same experience too btw.. I feed them something different everyday and make sure the temperatures are stable... "Craig Brye" wrote in message ...

when you post a question like the one you posted the so called experts
come crawling out of the cracks to give advice. i have been keeping fish for over 30 years and have had a small animal practice for 20 years. i do know a little about fish and i will tell you that giving your fish a live treat of brine shrimp or chopped worms (or whatever) is O.K. i treat my 240 gallon malawi tank about once every other week with live brine shrimp. in the wild they eat other things besides algae. i have been to africa twice and actually watched the fish in their natural habitat. take everything you read here with a grain of salt....... |

I feel the need to clarify as I feel you're directing this post to me. If you re-read my posts, you will note that I often said that occasional ingestion of insects or the like should not cause issue as in the wild these are occasionally eaten along with the algae. My posts were in response to another who seemed to be advocating a high protein/fat diet instead of a primarily herbivorous diet, which I do not feel would be in the best interest of the fish. I am an advocate of trying to replicate the feeding habits and diet that the fish would have in the wild. In the case of algae eaters, this would mean a herbivorous diet with the occasional "treat" of things like brine shrimp or daphnia would most replicate their natural diet. I'd also say treats of algae covered rocks would be welcome as then they could practice their feeding habits as well. Since the pet food industry makes it easy to replicate herbivorous diets with various spirulina products and so on, I don't see any reason not to do it (as opposed to say a mollusc eating fish, where it might be difficult to find sufficient snails/molluscs to feed without breaking the bank, so one has to settle for a flake food substitute not really based on a mollusc eater's wild diet). |

I do not recall anyone advocating a high protein/fat diet at all. I do recall folks advocating a herbivore only diet, which is probably not at all a factual diet in the wild. Seems like you were a cheerleader for the latter. Glad to see you see the light now... |

For that matter, do we forget our own words? Here's a refresher course. The following is the line from your post that motivated me to reply: Racf wrote: If all there was to eat was buffalo chips, I imagine anyone that liked them woud do quite well This prompted me to reply because such a diet is carnivorous and high in fat/protein. While I recognize you were not being literal about feeding fish buffalo chips, it still seemed to say that a carnivorous diet was fine and dandy for carnivore. That is why I had quite substantial replies about the biology of the fish, but never did I say it had to be algae and nothing else. In case you need a refresher, here's some snippets from my posts. From my first post: Cichlidiot wrote: The occasional invertebrate inadvertantly caught with the algae will not upset the intestinal tract to a great deal, but a primarily meat diet will. And from my second post: Cichlidiot wrote: Everything I've read about mbuna suggests that they do not have the capacity (ie the digestive enzymes and so on) to live on a diet consisting of mostly carnivorous foods without some serious digestive side-effects, such as bloat. The occasional intake may be tolerated, but not a constant diet of such food. So as you can see from those snippets, both of my posts on this thread said it was fine for the OCCASIONAL introduction of non-herbivorous foods. I was never a "cheerleader" for only feeding them algae as you seem to think. I have always "seen the light" when it comes to the fact that they will intake such foods on occasion in the wild. My point was while it is fine to feed such foods occasionally, the bulk of the diet should be herbivorous since this replicates their natural diet. My motivation was to be a counterbalance to your posts which seemed to advocate a carnivorous diet for a fish is an herbivore. Next time get your facts straight before you post such a gloating post as this one. |

I believe there have been quite a number of posts that balance the "herbivore" only myth that has been so pervasive for so long. Here is my original response on this subject in case you forgot: "I imagine the African's are not that much difference than their North and South American cousins. They pretty much eat whatever they can get.....with last choice going to Algae. I would only suggest a varied diet, and it looks like that's what you are doing." Save your "Bloat" for another day.. |

Lots of the Mbuna cichlids in Lake Malawi is the most Mbuna algae eater. Therefore, they should be fed on algae or other plants food. However, some Mbuna do not eat algae and many other Malawi mbuna have totally different than the demand for food.
