Four days later I bought some Mopani (although it sank ), soaked it over night and put it in. 2 days later, when the water darkened, they started glancing and the females went back to being relatively unreceptive. My water comes out of the tap at PH-7.5. Currently the tanks PH is 7.6 but I've done several wc over the last 2 days. So maybe it's not a PH problem. What is happening ?
If the wood came from a tank with fish, it may well contain protozoan (parasites and such). But if it was completely dry, this is highly unlikely, and I would consider other sources for the flashing (glancing).
A pH change from wood is not likely to occur to any great extent. Even in my near-zero GH and KH water, and with several chunks of Malaysian Driftwood in all my tanks, the pH does not lower beyond a couple decimal points, and this is more likely due to the organics anyway. Tannin release from wood may be strong initially, but this lessens significantly as the wood ages.
To try and pinpoint the issue here, we will need more data.
