Can anyone give me an idea of what my tank should have
How many what kind of fish male or female
Example 3 male endlers 5 unsexed neon tetras 1 male Betta three unsexed ghost shrimp
Well if your endlers are all male you should be fine
I can't see your tetras breeding to be honest, you CAN breed them in a home tank but they need rather specific 'blackwater' type conditions from what I've read.
You may get baby shrimps but your fish will probably just eat them.
