Hi all;
I've just been informed that we're redecorating the living room in the next month or two. I'm trying to treat it as an opportunity rather than a pain in the a***, so, as my LFS (a pet shop) has started stocking rather stunning looking Malawi Cichlids I think it's fairly well timed for a change. I have a 48" x 15" x 18" tank, powered by a Tetratec EX700 external filter (plus a spray bar). The calculator on the PFK site has given me a probable volume of 42G. I'm interested in a non-Mbuna tank, as I'd like a more open look and I'm not too keen on overstocking (or aggression). I'd prefer fish around 4" maximum. I've looked at a lot of tanks on t'internet and a lot of people seem to use ordinary gravel (some even seem to keep them in an ordinary planted tank). My water is at a constant ph of 7.2, and the water is described by the local water company as 'moderately hard'. I have three large pieces of Mopani wood, presumably that would have to go?. I've heard that ph can be raised to around 8 by adding baking soda, but how does this work - do you add it every so often, or do you have to keep adding it at water changes?. Be gentle with me, please. BTW, my tank (freshwater) has been up and running for three years without any problems.
 
Hi vinylman,

If you like the look of Malawi cichlids, there are 3 types - Mbuna, Haps and Peacocks. Unfortunately the adult size of Haps means they really need a 5 foot tank and Peacocks get to around 7", which is also a bit big for a 42 gal.

That leaves Mbuna, which you have ruled out :lol: - The good news is that all the colourful fish you have seen in LFS were almost certainly Mbuna anyway and there are quite a few less aggressive species. Here's a few examples:

Labidochromis caeruleus - http://www.cichlid-forum.com/profiles/species.php?id=1669
Pseudotropheus saulosi - http://www.cichlid-forum.com/profiles/species.php?id=1
Pseudotropheus Acei - http://www.cichlid-forum.com/profiles/species.php?id=1460
Iodotropheus sprengerae - http://www.cichlid-forum.com/profiles/species.php?id=707

Substrate in their natural environment is sand but this is not essential, although Mbuna love to dig so if you prefer gravel - make sure it's fine gravel.

Ph should ideally be around 8 but anything over 7.5 should be quite safe. Adding crushed coral as a filter media helps to increase/buffer the Ph - it can also be used as a substrate as can argonite sand, which will also buffer the Ph.

If you do go with Mbuna - i'd be tempted to add a second filter as Mbuna tanks tend to be over-stocked to reduce aggression and therefore over-filtration is also required.

This link to one of our pinned Mbuna topics should also prove useful if that's the way you decide to go. :good:

Thanks for that, Ferris; I didn't read the pinned Mbuna stuff, as I thought they were all aggressive. I'll read that now, thanks again.
 
They are all aggressive to some extent but the examples i gave you should live quite happily together in a relatively peaceful Mbuna community. :good:
