Tropical - Fish - Pictures .com

This is a tropical fish site for all tropical fish enthusiasts from beginner to expert. It has some nice tropical fish pictures and will hopefully have something of interest for all freshwater and marine fish keepers. These tropical fish pages provide some information about some of my favourite fish, along with tropical fish pictures of them. I have kept fish for many years now, ranging from community to marine. Over this period I have been drawn towards catfish, and the cichlids, which I must confess, through there antics have become my favourites. I now keep African and American cichlids, along with some catfish and plecs.

Tropheus Duboisi

Tropheus duboisi fry are very popular among aquarists. One look at them is enough to tell you why. Just 30 days after spawning, these fantastic fish show their characteristic black color with white polka dots.

The adults are black, with a white body band, and a blue head. Males typically have a wider bands than females. Another sexing trick is to look at the nose shape of the fish; The males have a slightly up-turned face shape, whereas the females are more round.

It is best to keep them in a group, 10+, in a large tank, 100 gallon +. Decorate the tank with lots of big rocks and a fine natural sand substrate. They like to eat veg material so illuminate the tank with a daylight bulb and a grow light to encourage the algae to grow faster than they can mow it down.

Once they start to mature, they may show interest in spawning at around 9 months, or about 2 1/2 inches. It usually takes the females a few attempts, before they are convinced holding the fry to term is better than getting their full share of food at feeding time. They can still eat while brooding, but are not as quick as the other fish and care needs to be taken to ensure they get a sufficient amount of food. Smaller food particles are much easier for the females to take into their mouths and will also benefit the fry as they mature and start to eat on their own. Brooding lasts for approx 26-34 days.

It is best to put the female in her own tank with rocks, and low lighting to settle her. Check that the water parameters are the same before moving her. She will release the fry to feed once they are free-swimming and she feels secure enough in her tank. Tropheus are very good parents and will take the fry back into their mouths anytime danger threatens.

Males are very persistent when it comes to getting a females attention; diving in front of her shimmying and shaking until she finally submits and they sink to the substrate or a flat rock on which to spawn. Here they will take turns circling and nudging while the female drops an egg then quickly spins around to pick it up, after which she tends to the male and fertilizes her brood.

Tropheus duboisi are a favorite of mine, among the Tropheus group. They are fun to watch interact in the aquarium, and who could resist those polka dot juveniles ?
