I can't really say specifically what I've done (if I've done anything) to bring this spawn on (presuming that there is one), but what I will say is that during this hot weather we've had, I've had to really keep up with evaporation especially as I've left the lid slightly open to allow some heat to escape. I also had a mystery fry death of one of the more recent babies, but it was at that age where fry seem to just die for whatever reason, so I wasn't TOO worried about it. All the same, I did a good tank clean and a series of water changes, using just room temperature water. I also tried to add a bucket of cold/room temp water every time we had a thunderstorm, just in case that had any effect. Whatever I've done, or not done, I think they've spawned again. Certainly looks hopeful... Watch this space!
