Always room for one more tank...
Ok, they may be found in large numbers, but is the wild the size of a 10 gallon tank? I think it seems cruel. I am sure a large number of Apistos in a larger tank would have the same effect.
If you look at the links I posted, you'll see this isn't me trying to recreate nature - someone else did that, and found that if done properly they can be perfectly healthy. When I say, 'someone else' I meant 'apisto specialists.' In nature it would appear that apisto's don't have territories, yet thats exactly what we create for them when we place them in a tank in the normal way.
I'd suggest people take a step down from their high horses for a second and consider this in a little more detail. Given apisto's small size, this would be no different to a heavily stocked mbuna tank - and I've yet to hear of the same people screaming that its cruel.
But yes, I'm a bad person for considering imitating a method advocated for experienced fishkeepers by other experienced fishkeepers, which in itself is an imitation of a long standing technique in practice in Malawi tanks all over the world. In fact I actually eat babies, and spend my weekends stealing disabled peoples wheelchairs. Could you please discuss it somewhere else though?
I like the idea of a sump sswm, although I agree sponge filters would probably an alternative. That depends upon room and resources really. What I'm provisionally thinking at the moment would be to setup a spare 65L (17 USG) tank with a load of indian oak or almond leaves as the substrate - a layer a couple of inches deep. Stack everywhere with (preferably new, unleached) bogwood to create a complete bogwood tangle, with the idea of it just being a maze of fish and wood. A couple of powerful sponge filters would complete that setup. As for numbers and species I'd have to look at doing a bit more research on that front. I don't know if I could mix or not - I'd imagine so. Numbers is a tricky one - whilst the figures quoted seem quite high, I'd sooner not push my luck. That said, you put too few in and you get the aggression issues. I think 30-35 would be a good number personally - enough that no-one has the opportunity to create territories, not so many that they haven't got room to swim about (bogwood tangle should help there, create countless avenues and areas for them to swim round.) And not too many as to overload filtration.
It goes without saying that I'd be testing regularly, and if it didn't work I'd have homes pre-planned for them. I am a conscientious fishkeeper and whilst the project in itself would be fun, all my fish are kept as pets - not wall decoration.
Does anyone have any practical improvements? Don't hold your breath for photo's of it happening though, I intend to take my time planning
