Wish you had mentioned this before convincing me to buy them

So far so good with my 6 but they are not breeding yet. I think the bubblenest I spotted was a trial run.
To date the aggression is mostly contained within the group. They do occasionally chase the boraras so I am keeping an eye on this. I have not seen contact but one of them does have a rather suspicious chunk out of its tail. If that escalates they (the boraras) may have to go and live with the CPD.
I still have space in the big community tank if I need to split them out. The only other option is in the 20G with the swimming highlighters, I know this works for you but I also have dwarf chain loach in there and I suspect the sparklers may have a really tough time with them.
