You are very limited as to what species you can keep in that size tank. These fish are highly aggressive and very territorial, and the options we've listed so far are about the only ones you have as far as cichlids from Lake Malawi go...
The only reason we recommend as many demasoni as we do is because they are dwarf mbuna, and must be kept in larger groups to control and disperse aggression. This doesn't mean that you can substitute 10 other species for the demasoni in a tank!
You'd need a minimum 4 ft tank for most of the species listed, and would have to be very careful choosing stock from that list for even that tank size.
see this is why i asked the question as i havn't got a clue on the speicies side of things
so possiblities are:
10 Pseudotropheus demasoni with 3 yellow labs????
Pseudotropheus saulosi ( 1 male with 3 to 4 females)
^^^^^^^can these be mixed with Pseudotropheus sp. msobo as thats what is pictured together in the speices photo????
"You are very limited as to what species you can keep in that size tank. These fish are highly aggressive and very territorial, and the options we've listed so far are about the only ones you have as far as cichlids from Lake Malawi go..."
So what could be my options from the other lakes/places??
If you did Lamprologus ocellatus, you could put some leleupi in probably as well, providing you made 2 separate territories. I'd post about this in the Tanganyika forum(as that's the lake those fish come from) and they'll be able to tell you how much of what you can put in. A tank that small would really be much better off with a smaller Tanganyika setup IMO. Check out my 29 gallon cube tank in my "tanks" link.
If you go with saulosi, those are the only fish you would need in that tank size. Ps. Msobo females are wicked aggressive, and wouldn't work at all in a tank that size, even if kept as single species.
There are several species from Lake Tanganyika that would be suitable, you won't get the colour you are looking for (blue and yellow), though. They are very interesting fish - beautiful - but not as colourful. Take a look in the profile listing at N. brichardi and some of the shell dwellers.
personally i think mbuna such as demasoni and salousi can be done in a tank that size but its not really givving them a good replica of their natural habitat...
:fish: Lamprologus Ocellatus (or other shelldwellers)in my opinion would be a great choice as your tank size is plenty to observe their fascinating behavior etc.
+ you could add a pair of rockdwellers like julies or comps/calvus...
Although it has been done, I would not do any mbuna in a 30" tank. I had mine in a 36" tank and felt it was too small. I agree with aaxxeell, I would do Tanganyikan shellies and a pair of black calvus.
