Hello! 
I have been searching about the famous firefish for a while and how many can one place in his DT..
There are so many opinions :
Some say : only one by tank
others,by couple,if you were lucky to get a male and a female..
And others say that they do the best when they are in odd numbers..
Also,what about mixing red firefish and purple firefish?
Also lots of disputes to this part..
What do you think?
Thank you!
