i have a 20 gallon tank with a power pro 30 gallon filter and plants. i have 6 neon tetras 3 tiger barbs 4 zebra danios 1 cory and 1 whiptail catfish. is this to many fish? all of my fish are real active and they seem very happy my cory takes care of leftovers and the whiptail takes care of the algae and i change the water every week.

i would get rid of the tiger barbs and the whiptail cat fish.. the genral rule is you take the adult size of the fish and the gallons of the tank so lets say you have a school of 6 fish whos adult size is 2 inches thats 12 total inches 20-12=8 inches left. the barbs are two agressive for the tetras and dainos. and proubably would be better in a 29 gallon and in a group of at least 5. the whiptail gets longer bigger but im not sure if you would have to get rid of it,. the cory would be happier in a group.. i would stick with neons get two more dainos, and then get rid of the barbs cory and cat fish and get some ghost shrimp or some type of smaller shrimp since they will scavange and eat algea and wont affect the bio load. cherry shrimp are attractive but can be pricy ghost shrimp are normaly cheap and have there own beauty in a way, how much water are you changing every week

i think ill return the tiger barbs but im keeping the whiptail he is way to cool to return and ill probably get ghost shrimp. every time i test my water everything is just off of perfect which is normal or atleast the store person told me it was

This will be probably be okay. The whiptail will likely be alright, but they are pretty sensitive to water quality issues, so I would suggest getting an API Master Test Kit so you can do your own water tests (pet stores often mess up water tests).
