Roxanne and Thomas' fish Roman were exhibiting spawning behaviors last week, but after I did a water change the mood seems to have been ruined. They're in the "let's just be friends" stage! I had really gotten used to the idea of fry and was very excited, so the fact that they stopped has me sad. Roxanne dropped only a few eggs (maybe a dozen) and it doesn't appear Roman did his part. I removed them, in hopes that there would be more... but there's not!
I turned up the temp a bit, and that didn't seem to help. Is there any way I can encourage these two to resume their former activities?
