My dad has a 500 gallon tank in his basement that I took care of a ton and know pretty much everything about.
10-15 Rose Anemones
1 14" Red Sea Soft Leather Mushroom
Tons of green and orange polyps
About 20 Superman polyps (worth about $100 each. My dad is trying to get them to grow like our others that we've had for about 5 years and have completely encrusted some of our rock and look super cool)
Austrialian White Lightning Sponge (Look it up, coolest thing ever.)
2 Peppermint Shrimp
1 Harlequin Shrimp
6-7 Emerald Crabs
1 Sand Goby
1 Naso Tang
1 Copper Banded Butterfly
6 (1 Male and 5 female) Pink Anthias
3 Ocellars Clown's
1 Purple Tank
1 Blue Tang
1 Striped Tang
2 Cardinal Fish
1 Mandarin Goby
1 Blue Spot Jaw Fish (My Favorite fish)
Lots of small different colored Ricordia??? sp. mushrooms
And thats all I can think of for now.
We had 2 pipefish like 4 years ago but since then my dad has changed to a higher flow tank so they went back to the store.
