Hi!
I've decided that I might as well post a journal for my Saltwater Aquarium. These are kept in a 25 gallon Saltwater Mud Flat set up, and the filter isn't a Protein Skimmer or anything. It's just a normal filter, and I think that simulates the Mud Flat environment better.
The only fish I have in there is a fish called an Aholehole, aka the Hawaiian Flagtail. They are quite common in reef areas, and I caught mine as a small fingerling at about an inch. She is now about 2 1/2 inches. Their full size is 7 inches or so.
I also have a Fan Worm, which a species of tube worm which sends out long, featherlike feelers to grab tiny food particles. Mine just shed his feathery crown (the feathers), an occasional occurrence similar to shedding skin. I don't think he has grown, because I found him as an adult.
Surprisingly, I also have a young Mantis Shrimp in my aquarium. He doesn't ever attempt to kill any of the aquarium inhabitants. He only comes out of his little burrow to grab fish flakes, most of the time you can only see his eyes peeking out of the crevice.
I have 2 hermit crabs, one of which I caught as a young crab and the other I caught in its planktonic stage (When I was getting water from the beach for my aquarium, I noticed it skimming the top). They are both pretty well sized now.
My aquarium has an infestation of sea squirts, which is pretty weird if you ask me.
I used to have a shrimp (I think it was one of the half-transparent native bait shrimps of hawaii). I released her a few weeks ago.
The first fish I had in my aquarium was a tiny pufferfish that I caught at the beach. Sadly, it died of a Marine Ich(cryptocaryon), which is a dangerous fish parasite. He lived for several months happily.
I have a bunch of sea snails (Pipipi (Nerita Picea), a Pipiwai hybrid (possibly a hybrid of Theodoxus Cariosus and Theodoxus Neglectus. T. Cariosus is rare, so it is pretty interesting to have a hybrid), and a pure Theodoxus Snail. They are all what is called Nerite Snails. There are also a few predatory snails that eat the leftover fish food.
Thanks for reading this!
