OK, well none of the fry made it, though a few made it longer than I thought (found them swimming amongst the floating plants).
But the pair already spawned again! Is this going to keep happening or will there be a time where they give it a rest? How frequently do spawning pairs spawn?
If they keep going at this rate I'm going to have to rehome the Apisto as it's not fair to him to be continually chased. There are hiding spots, and they've done no damage, but when they are spawning they chase a lot more. When they're not spawning there's minimal problems, maybe a bit of food guarding but that's about it. If it was only going to be here and there, he'd be fine, but if it keeps happening like this he'll never get a break. I definitely did not anticipate this.
Looks like I have to get that fry tank going sooner than later...
