Ok, I went to petsmart today and I saw the cutest thing in the entire world!!! a dwarf platy!!! has anyone heard of these

? they are like half of a regular platy and look pretty much the same... but in a little package!!! I was looking on adding one more platy for my tank since I have 2 platies and on eof them is kind of a bully against the other one. But since I had almost no more room left (a platy would have been too much since they are like 2.5 in)... This little thing could be the answer to my Prayers

?? according to the tag it grows no more than 1.5 in!!!!
anyone heard of these cute little babies? Would one get along with my regular-sized platies?
