Not even some experts should try mixing species. You make this sound like, it's something we work towards, like if we have 20 frogs, we can try a community tank. Heck no! I know very few people who mix frogs aside from local frogs. It's not a good idea. and you're "big" 50 gallon, lol. Go get a bush. I have a 120 vert, that I think could hardly hold a normal sized bush. You should not mix species. Period.
