Setting a Tank Up for Mbuna – Rock-Dwelling Cichlids of Lake Malawi

PolitHey out there! This time around I’d like to talk about setting up a tank for Mbuna, or “rock dwellers”. You can find these colorful fish in the any of the three rift lakes of Africa, but for this blog we will talk about the preferences of species from Lake Malawi.

First, the tank. Larger is better for a couple reasons. A 55 gallon is nice, but a 75 is better for these fish, with its 18 inch width. narrow tanks can be a pain since you’ll want a lot of rock for these fish. The second reason would be that the more room you give them the easier it will be to control aggression. I was once told that if you crowd these fish, they wouldn’t be as aggressive, not being able to single out others to target and bully.  I have seen Mbuna tanks with 12 to 20 fish dwindle down to 4 to 5 fish due to dominant fish. I think it depends on the species and particular fish that you’re trying to house together more, and I don’t think crowding is ever good advice. Last but not least, the larger the tank the more choices you have when it comes time to choose livestock. Read More »

Four of a Kind – Our New Batch of Rhamphochromis

Rhamphochromis macrophthalmusThe thought of a freshwater counterpart to the stealthy marine barracuda is just awesome to me. There are several fish called freshwater barracuda, but in the world of cichlids, Rhamphochromis fits the bill. So, I tend to get excited when I hear anything about Rhamphochromis, especially when they arrive in the store. I’ve never kept these fish, but I can see them in my future. Here are some things you may want to know if you’re as intrigued as I am. Read More »

My Top 10 Favorite Malawi Cichlids, From the Mind of a Cichlid Mad Man

Hey folks, as promised, here’s the first installment of my favorite fish! Just remember everyone’s opinion differs and I would like to see other peoples faves,  too, so please leave a comment if you have an opinion.  Here goes, (in no particular order)!

Copadichromis azureus – This haplochromine is a zooplankton feeder. Males attain a length up to 8 inches with females around half that. A colorful fish, males sport a metallic blue with a white dorsal edge and black fins. Also sold as C. chrysonotus.  They are as attractive as they are interesting to watch.

 

Protomelas insignis juvenileProtomelas insignis – Also known as P. spilonotus (Tanzania) this particular hap attains a length of about 10 inches, with females at 7.  Males develop a bluish green head with 3/4 of the upper body dark blue while the bottom 1/4 is yellow. Beautiful!

 

Pseudotropheus polit – This feisty little Politcave brooder, which tops out at 4 inches, has a nasty napoleon complex. Males become a very light blue with a black face. This fish will keep you on your toes!

Aulonocara ethelwynae – This peacock attains a length of 5 inches, and has an understated beauty.  It is not a very colorful fish, as compared to other peacocks. The body is mostly brown with some yellow accents, and it has a blue lower jaw. The fins are their most attractive feature as both the anal and dorsal are blue to a light purple in color.  A fish that lives around the sandy areas of the lake,  it also needs rock for protection and breeding.

Dimidiochromis compressiceps – This piscivore (fish eater), which is also known as the Malawi Eye Biter, attains a length of 11 inches and is rarely encountered in the rocky habitat. It mostly frequents reed stands and vallisneria beds where its laterally compressed  body can allow it to hide as it stalks prey. Males develop a metallic blue face and body, a white dorsal edge with red tips, and a red anal fin with blue white egg spots.  What is not to love about this fish!

 Nimbochromis livingstoni juvenileNimbochromis livingstoni – This 11 inch piscivore has an intresting hunting behavior, and is a blast to watch in action. It partially buries itself in sand and feigns death. It has a mottled pattern of brown blotches on a pale body.  The pale color attracts smaller fish, which are then caught with a sideways thrust, like lightning! Dominant males develop gorgeous dark  blue coloration.

Tyrannochromis macrostoma –  Another predator, this species attains a length of 14 inches and has a peculiar hunting technique, also spectacular to observe. It hovers in a head-down vertical position and tilts its body to one side.  The position allows this hunter to observe its prey in the rock and snatch it out of its hideout.  Males are a blue with yellow-orange in the anal and pelvic fins.

 Protomelas steveni juvenile
Protomelas steveni (Taiwan Reef) – This awesome species hails from three different areas with differences in colors. Higga Reef variants are all blue with a red anal fin and a white blaze, Ngkuyo Reef variants have a blue head some blue in body, while the back and belly are both yellow, and the anal fin is yellow. Taiwan Reef is my favorite, featuring a blue face and back, yellow body, red anal fin and a white blaze. Simply gorgeous fish. There is also an albino version which is stunning.

Rhampochromis sp. – Open water predators, these “Malawi Barracudas” range in size from 10 inches to 18 inches. They are mostly silver, though a couple species also have yellow anal and pelvic fins. They’re made to chase down prey, natural hunters you can’t help but to admire.
Any Lethrinops sp. or Tramitichromis sp.- These sandy living species come in all “flavors” and I will always have a soft spot for them for the variety of color they exhibit and their unique and interesting behaviors. My favorite variants are the Tramitichromis ‘Red Flush’ and the Lethrinops ‘Auritus Lion’.

In closing, lets not forget that these are my faves I would love to hear from anyone who reads this blog about their favorite Malawi species and variants, please take a moment to give your take in our comments section and as always if you have any questions, let me know! Next up are my favorite Victorians!

Copadichromis Cichlids: Breeding Observations

Jose MendesPlease welcome back our “Cichlid Guy” Jose with an article on his experiences with Copadichromis species.

In Lake Malawi, there is a group of zooplankton feeding cichlids known to the natives as “Utaka”. They are the most important and most successful group in the lake. As where most cichlids are bottom dwellers, they have developed into an open water species. Utaka have developed several breeding techniques. Some breed in the rocky habitat and some construct sand bowers in the intermediate habitat, while others breed on the open sand. A fourth strategy is employed by Copadichromis chrysonotus. It is the only known Utaka that spawns in the open water.  In the hobby, young chrysonotus have been confused with young Copadichromis azureus. I have had the pleasure of working with both species, and they are different in size, color, mouth structure and breeding behavior. While the azureus bred under a cave (where he would lure the female with figure eight motions), the chrysonotus bred six inches above the rocks. As much as I enjoyed working with this fish, I have always wanted to breed a species that utilized bowers. The species I came across is Copadichromis eucinostomus. It is found in Lake Malawi, and was previously known as Haplochromis eucinostomus and Nyassachromis eucinostomus. It is found throughout the lake where it feeds on plankton, and its habitat consists of sandy areas in shallow water where males construct “sand castle nests”.

Spawning takes place in the early morning hours. After the eggs have hatched, mouth brooding females congregate into nursery schools and release their fry simultaneously in very shallow water.

After acquiring a wild pair from work, I put them into one of my 75 gallon aquariums. The tank was decorated with caves and a fine Aragamax sand substrate. The water conditions were as follows: Ph 8.8, a hardness of 200 ppm, and a temperature of 82 degrees. Their diet consisted of different flake foods supplemented by occasional feedings of frozen brine and mysis shrimp.

After about one month, the male started piling sand into a mound in a corner of the tank. His color then began to intensify. He went from silver with a light blue face to a light blue with yellow dorsal and caudal fins. From the lower jaw to the anal fin he was black. He then started courting the female to his nest, where she deposited at least two dozen eggs in the normal mouth brooder fashion. At about 27 days I noticed some fry hiding in the rocks. I then removed the rocks in order to catch the fry. I captured 17 fry less than 1/4” in length. The fry then went into a breeder net that was hung in the same tank. They were fed crushed flake and baby brine soaked in Selcon. They ate very well and never turned down food. After three weeks, I transferred them into a 10 gallon tank for growth. This species is generally peaceful at 4.5”. Their max length is 6”, although in the aquarium they can probably get larger. It is definitely worth keeping along with Aulonocara and certain Malawi haps. They are not common along the East coast, but you might be able to find them through forums or specialized clubs dealing with cichlids if we are not able to get them for you. Copadichromis are great looking fish with interesting breeding behaviors. I would recommend if you keep African cichlids to give this family a try, you won’t regret it.

Thanks Jose, as always we look forward to future tales of your experiences.
