I have 11 platy fry in a 21 gallon tank, they are about 2cm or 3cm in length, they were born on the second week of january, what would be suitable tankmates? Ph-8
I suppose you are asking us to reccomend a gourami tankmate as you posted in this section?
You could get a couple of dwarf gouramies or a trio of honey gouramies or a thick-lipped or banded gourami or a pearl gourami and not be over-stocked with 11 fully grown platies included.
Yes, 1 male with 2 females is best. HOWEVER, you CAN try 3 males if you realy want to but be prepaired to offer lots of floating plants for hiding and retreats and be aware that things could go wrong - make sure you add them all at once as well. Might I ask what the problem is with keep 2 females and 1 male?
