Let's see... too many...
- 150g, mixed reef with an assortment of reef safe/reef safe with caution fish, a Linkia, and a giant coral banded shrimp named Leviathin.
- 65g, soft coral tank with fish, invertebrates, and a fromia (this is my favorite tank, can't remember if it has been running 3 years? 4 years?).
- 20g macro algae, soft corals, LPS tank with a serpent star, snails, hermit crabs and a blue coral banded shrimp. That is it because the micro fauna in that tank is soooo fun to watch!!!
-50g freshwater Axolotl tank (compared to the other tanks, this one is soooooo easy to take care of)
- Bowl with Axolotl eggs. Does that have to count

?
- 40g that had a crash a few months back and I am going to tear down today. Someday will be replaced with the 57g rimless in storage that will be a SPS and invertebrate tank with no fish.
We have had 8 tanks running..... now that was way, way too much to take care of for us. I finally had enough and tore down 3. The list above is pushing it.... 4 saltwater, 1 freshwater, and raising baby axolotls is our absolute max of what we can reasonably take care of. 3 saltwater would be better.......... also wish the Axolotls hadn't laid eggs.
