Hi there!
We've had goldfish for quite a while in an outdoor pond. Started with 2 feeders from Walmart and now have 4 big ones!
A friend gave my child a betta as a gift but it didn't survive the week.

We have a planted, 5 gallon, filtered, lighted, heated and, now, cycled aquarium for a future betta friend! So far a few snails live in the tank from the plants we got. The nice thing about the snails is that we can put them in the pond, as needed. i think our goldfish like the tasty treats.
We are hoping to buy from a breeder

rather than try our luck again with the big box stores.
