Well let's see 5 phantom tetras would be about 10" of full grown fish, 4 neon tetras would add another 6", then 4 highfin platys are 6" more, and 5 more platys of various types 10". That is 32" of full grown fish already and we haven't even gotten around to the snail and the catfish. I would have to say your tank is already full. I am sorry to say that there is no room for any fancy guppies. I do know that they are very beautiful but I am afraid you may have to admire them in others tanks, but wait.....it is a perfect excuse to get another tank

. We all do develop
MTS (Multiple Tank Syndrome) here sooner or later.
