I have a friend interested in some sparkling gourami, so I may see if perhaps she wants this girl and one of my male fry for a pair. It would mean this girl will go on to have a bigger home, but it depends if my friend wants her.
Everywhere read says to get a group not pairs, or single, so... but i know someone else who has had aggression problems too where the least dominant individual got killed too, so perhaps they're not as "social" as sources make them out to beWish 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.
