Long. 4 babies - 1 black moor 2 cal. Fantails and 1 red ryukin. 350 penguin
All four are babies. I have high filtration and do weekly water changes.
No. Ive been running tanks for 3 years without.
Shouldn't** I change about 50 percent
Again, they will be move to a pond. It would be rather stupid to try to fit full grown goldfish in a low 20 gallon. That rule of thumb is based on a required filter. Some Nitrates turn into plant food. Thats how I can keep 4 fancy in a 20 gallon.
P.S. this is experienced based, not something you read off the internet. I know what I am doing. Im looking for more information on success in planting. Not info for noobs to the hobby.
Then explain to me how my tank is clean and goldfish and plants are healthy?
