The threadfin cardinals are 2 females and 1 male. Not a good combination.
The 2 females try to persuade the small male to hold their eggs and this means that the larger female isolates the smaller one.
I wanted to have a much bigger group but most of the fish I got just wouldn't eat at all.
I will stick to my decision of not adding more fish, not because of the sake of keeping my word, but because these fish don't acclimate easily and the risk of bringing diseases to the tank is high.
