Tiny juvenile Oligocottus macuolosus, tidepool sculpin
One of my favorite things about these fish is how delicate their mouths look when they’re little.
Watching the kelp forest exhibit gives me life and it’s teeming with life!

Beautiful koi coming to check me out at Deep Cut Gardens.
Ignore my reflection. Best photo I could get for now as I had to check up on the spawning fancy bettas. Male was in that elodea batch up top. Still plain but will add more driftwood once I get the chance to go to the feed store. They have the best driftwood price. Only $2.50 per pound compare to $8 at my other LFS. Plus, I can usually get a better deal if a friend works that day. Waiting on my IAL too.

Most people who are new or not into fish keeping say,” I don’t want big fish tanks, because they require more work!”
More water makes it look that way, but the truth is that larger tanks are easier to take care of.
What, but how?Imagine that the red dots are how much waste Mr. Fishy creates in one week- that’s 9 dots. On the left is the waste in a small tank and on the right is the waste in a big tank. The water in the small tank is more toxic because there’s more waste per part of water, but the big tank has less toxic water because there’s less waste per part of water.
What does this mean?
For the small tank, more water changes have to be done weekly to keep water safe for Mr. Fishy.
For the big tank, a smaller weekly water change is only needed to keep water safe for Mr. Fishy.
Here’s a weekly water test from a divided 15 gallon tank for two Siamese fighting fish (betta splendens):
Aside from pH (which should always stay constant), all of the toxins are at zero in my filtered tank. That’s always to be expected from any mature tank. But look at the nitrate! By the end of the week there is nearly zero nitrate, plants help but the size of the tank helps even more. If I didn’t change my water for 3 weeks, the nitrates would still be below 20 ppm- but I still do 10% water changes every week. I don’t have to worry about any catastrophes rapidly occurring.
But my fish doesn’t like big spaces!
If you get a bigger tank, fill it up with plants and ornaments to make your fish more comfortable. If your fish is not doing well in a big tank, it’s not because of water volume. A big empty tank is going to be scary for some fish, a small empty tank can be the same.
Tl;dr: Bigger volumes of water dilutes the daily/weekly amount of waste your fish creates, meaning less frequent/smaller water changes and more stability.
Holy dragon veiltail. Someone buy him for me.
Working on a large stone pond commission. These fish were based off someone’s koi. I really like the reddish orange one. :) #handmade #polymerclay #miniatures #fish #koi #wip #commissions
One last shot of this cool little guy. (Trichoptera, Helicopsychidae, Helicopsyche). Pratt’s Falls, NY
Helicopsychidae are clingers, with the larvae living in the portable cases pictured above. Because of how similar their cases look to snail shells, this family was actually originally described as a snail. The helical shape of the case improves resistance to crushing (Voshell, JR. 2002).
