Attaching a few pics of my attempt of a planted goldfish tank. I'd love to get people's opinions, as well as receive any suggestions to make the tank look better, bearing in mind it's not easy with a goldfish!
I have a normal goldfish (non fancy), so needless to say he tears up or eats most plants (which I found the hard way over many month of experimentation). I found a good balance now with Java ferns and different types of crypts.
One thing that really helped me was potting crypts in a glass container, so that I could offer quality soil substrate with root tabs, because using soil substrate across the whole tank isn't an option with goldfish! Also make's it easier to clean, since they're quite messy. This is a 10 gallon, I will upgrade shortly (I know it's small for a goldfish, but compared to the fish bowl he was in this is way better!)
