With corys and angelfish alot of times preforming a water change with water that is a little cooler will cause them to spawn, if they are in condition etc. Is the same true for cyprichromis?

I have, both, heard and seen this. I think it mimics a seasonal change which will spark spawning activety. :fish: :idea:

I haven't tried cooler water intentionally, but I have found that a neglect-care cycle works pretty well. When I leave for a week or more, I have someone check on the fish a couple times a week and only feed them sparingly. So, no lights, little food, no water changes. When I get back, I do large water changes and about a week after that I see many holding females (for gobies, paracyps, cyps, xenos, etc).

I think the change in water temp triggers most species into breeding or a large water change. Either of these changes haved worked for me over years especially with Frontosa's. My temp is changing during a WC because I have to gauge temp with my hand straight from my faucet. Which I bet happens in about 80% of the tanks out there during a WC. The difference wil depend on someones feel and the % of WC to tank volume, unless they have a temp gauge.

I've got 3 kitumba fry since I had my cyp's over the past 9 months. One female held to term the first time and has not bred again. The other 2 have not held for more than a few days :( But I only have 10 right now and the biggest is about 3 1/2". I vary my WC schedule like Triscuit's talking about, to quick small volume changes for the next week. This way I attempt to cover all the different water depths the fish in my community tank are used to. ie: gobies and Furcifer's come from the shore, and the fronts come from deep water.

Hopefully I'll get some fry.

But gobies, all you need is water. I've never seen such a prolific fish. The most I've seen them wait is three days after the male releases and she is holding. They have been through this cycle 6 times now. There must be a gazzilion of these in the wild, or some fat bellied Fusco that came in for breakfast :D

The reason it works with south american species is that most come from smaller streams feeding the larger rivers like the amazon, so a rainfall drastically changes both the temp and hard hardness (dropping it vastly) and pH.

A heavy rainfall wouldn't dent the temp, pH or hardness in Lake Tang and most species becuase of this don't seem to even like large water changes (at least in print, many aquarists don't seem to have this problem). But because the lake is so stable, I don't imagine it would have the same effect.
