Buckman Posted January 7, 2022 Share Posted January 7, 2022 Hey everyone. I have had a 20 gallon aquarium for about 6 to 7 months now. Finally settled in well. I started with 10 Harelquins and 9 are left. I recently bought a new heater to make sure the temp didn't drop in winter. Maybe it is the added heat, the tank settling in, or both. But they looked extremely frustrated trying to dance. They pair off and then fight a bit. I have even seen males separated from the group for a long time in a thicket of plants. It doesn't last more than a few hours, and I have never located the eggs. There is a fairly new female betta added to the mix that seems to like to disturb all this behavior. So that doesn't help. I would like to breed them, but not right now. I don't thing I'll be able to separate anyone or have an extra tank for this until Spring. So I have a few questions. 1. Would getting a 10th calm them down, or make it worse? 2. My new fluval heater is the one set at 80 degrees. Do I need to pull that out and reduce the temp a couple degrees? And finally, when I do get another tank to maybe make some more... 1. These guys are in water that I have made hard with crushed coral. Was looking to stabilize pH with high light and CO2 going on in here. It helped a lot. But from my reading, if my harlequins want to breed in water this hard, they must be from farms in Florida and not from South America. So, when it is time to breed them, can I dispense with then soft water parameters? Or is this a hard stop and part of the reason why they seem frustrated now? Thanks in advance.
