Let's hear about your terrariums, ecosphere's and aquariums used as terrariums here. Are they flourishing? Diseased? What do you feed them and how do you maintain them?

Rockoe10 you can go first...

Well it's me instead..I used to keep king snakes and tarantulas..even built my own cages..
I would collect mice from the barn for the snakes and the spiders would eat just about anything.
When I was a little kid we had a small black jumping spider that lived in the corner of the ceiling.
Come meal time it would crawl down and eat wee meat snacks next to me on the table.
I kid you not it's true.

Ooo spiders and snakes! An old roommate of mine has lizards and snakes. Uuugg i couldn't take the smell personally. I find reptiles cool, yet stinky. Now i think spiders are amazing. I would love to have a little Jumping Spider. I used to have a scorpion in college, which was fun but i learned that they weren't for me.

When my daughter was born, she wanted a fish. I had never had fish growing up so i had to learn so about the nitrogen cycle and fish keeping. I have found Dr. Wahlsted's methods to work perfectly. I raised 10 generations of guppies over 6 years in a couple planted tanks. Hoping to create my own line/breed of guppy. I really enjoyed it, but my wife says I have too many hobbies , so i downsided this week to make room for my gardening and gave them to my sister-inlaw.

I did keep my minuture aquarium and Ecosphere though. The smallest one is 5 years old and doesn't receive any extra input. well, that's not 100% true. I check on it once ever year to make sure it's still viable, by adding a couple fish food pellets if needed.

I used Acute Bladder Snails as the bottom feeders for all my tanks. And it's the only animal in my Ecosphere. She/he does just fine and is self procreating.

I grow,
Bacopa monnieri (Money Wort)
Cryptocoryne pontederiifolia (Leafy)
Echinodorus (Assorted Sword)
Microsorum pteropus (Java Fern)
Vesicularia dubyana (Java Moss)
Hydrocotyle leucocephala (Vine)
Frog bit (floating plant)

In my Ecosphere is Java Fern and Frogbit.

When i still had the open top fishtank, i also had Golden Pothos growing from it. I rarely had to do water changes.

My wife misses the fish now and says I should get a Beta for the 1.5gal jar. Its a Lemonade/Tea jar and makes for easy water changes. Our first fish was a Beta that we kept in a jar just like this. He lived a LONG a healthy life. Its amazing just how much better an aquarium will do when there are living plants in them.

My spiders and snakes were outside.
They always got let go before the cold set in.
I could always catch more the next spring.

Sorry for the picture spam. I went through one photos. I commented them.

I also had a "Muppy". Its a hybrid between a molly and a guppy. Very rare and unfortunately she was sterile. I wish i could find a picture of her its not on the phone...
