Keeping different species of same genus in same tank?

I'm in the planning phases of a 92 gallon tank and while I've settled
on Lake Malawi Cichlids, I have a lot of questions.

Today's question is on the multiple species of the same genus in the
same tank.

I'm leaning towards a "peaceful" Lake Malawi aquarium and while using
the cichlid recipe (Matt Pederson should get a gold medal for this
site) and also the Cichlid Aquarium (Loiselle) and also fishbase.org,
I've noticed some "warnings" about not allowing different species to
reproduce, I was wondering if one would be able to keep trios of
different species of the same genus.

My assumption is that as long as their own species exist, then they
will stick with it. However, assumptions have a ways of being wrong
most of the time ;-)

I was wondering if anyone out there successfully kept multiple species
of the same genus (in my case, I'm liking the auloncara's) ) in the
same tank.

These are such wonderful, brilliant looking fish, that it would be
nice to have 2 or 3 species, but if I have to, I would keep only one.

Other species that I am currently researching are:

Copadichromis (Utaka)
Labidochromis
Protomelas
Julidochromis (I know these are Lk Tanganika, but I would like some
bottom dwellers)
Neolamprologus (non-shell)
Lethrinops

With a 92 gallon, I should be able to get 4-5 sets of trios of the
above genus, but was wondering if I could intermingle species of the
same genus, as long as I keep trios of each species.

Sorry but your assumption is not correct.
In a same genius, one male fish will become the "big boss" and reproduce
with every female regardless for their species. So, if you don't intend to
let any of the new generation fish leave your tank, it's not really a
problem. But if you start exchanging fishes with other cichlid-freaks, you
will introduce hybridization.

Sure you can keep different species. It isn't dangerous to the fish,
but you always risk hybridization and, thus, the production of useless
fish. Even with trios. the first generation of fish will grow old
and pass on, and then you could be stuck with a 2nd gen. of colorless
half breeds .

I have a 92 gallon established and your definition of peacefull
may be different then mine. Malawi cichlids fight. Period. The only
way I have found to keep the fighting to a minimum is to crowd the
tank a bit, and do more frequent water changes. I have a mix of
malawi, south and Central american and even a couple west african
riverine cichlids, ranging in size from 1.5" to 3" in my tank. (about
20 fish in all. And they do just fine together. Others may not
agree...but that is half the fun....your tank will be different from
everyone elses in both appearance and behavior.

Well, "peaceful" is a relative term. When I say peaceful, I'm
comparing them to the following:

Labeotropheus
melanochromis
Nimbochromis
Petrotilapia
psuedotropheus

From what I've read, most of the above genus are more agressive than
what I'm going for, hence the word "peaceful". I know that I can't put
a lot of other small fish in, even with these "peaceful" cichlids,
otherwise I'm just using expensive fish food ;-)

I'm really curious as to what you have in your tank. Do you have a web
site or if you could reply here that would be great! I"m always
looking for data points to compare with what the cichlid recipe says
and see what others have done in their own tanks.

Bernard - thanks for clarifying my assumption! I guess that tells me
what I need to know. I will plan on having only one trio per genus.
While I'm not in this for breeding, we all know it's a consequence of
keeping fish together in an aquarium and "IF" they breed and the fry
survive, then I would be left in a quandry if I kept mulitple species
together. I wouldn't want to give them to anyone and I'm not sure I
would want to keep them myself.

Thanks again!

Don`t mix several species! They mix and the hybrids are only worth for
feeding-fish.

In my overcrowded 110 gal Malawi i have one (!) pair of aulonocara
jacobfreibergi constantly breeding with lots of kids and 1 labetropheus
fuelleborni with 2 male w and several kids. This is o.k., but:

In the beginning i added 1 melanochromis johanni and several pseudotropheus
zebra red/red; They seem to mix somehow and the hybrids are useless and look
ugly. So you better be careful with that. You should not mix species. 3
Genustypes (spell?) are enough. Each should be 1 m/2 w and you will have fun
in your AQ.

In my experience with Aulonocaras, there is a dominate male in full color in
the aquarium, and the sub-dominate males show much less color than one would
hope. I have kept them in aquaria ranging in size from 30 to 100 gal in
size.

Keeping fish from different genera will not insure hybridization will not
occur. I have found fry in a tank containing only Pseudotrophus aceii and
Labeotrophus trewavasae.
