Freshwater and Tropical Fish
I currently have a 30 gallon aquarium with two platies and three guppies along with a nerite snail in it.
I also have a 10 gallon with 2 cory cats and 7 gold zebra danios. My goal is to combine these into the 30. Will the 7 danios at one time give too much of an amonia spike? Should I do them...
