My son brought these fish home from school after working on a project for about a month.

He had grown attached to them and didn’t want anything to happen to them, so now I’m trying to figure out how to care for them. I’m not sure what kind of fish they are or what size tank they need, and there’s also one smaller fish not pictured.

I’m on a tight budget, but I want to give them the safest setup I can.

What would be the most important first step?

Advice needed from the deck people.

I’m building this deck myself and I’d say I’m fairly capable, but I noticed an issue right as I was about to start picture framing the stair treads.

I have 9 stair stringers spaced 12” on center. They are level with each other, but they’re off level compared to the main deck by enough that I think it will be noticeable. The heel side of the tread will sit higher and the toe side lower.

Everything is already secured, so now I’m trying to figure out the best way to correct it without making a bigger mess.

The bottom of the stringers is attached to a 2x10 that’s anchored to a trench footing with Tapcons.

Would you remove and notch the bottom of the stringers to key into the 2x10 base plate, shim the top of the stringers, or handle it another way?

I appreciate any productive advice before I go too far with the treads.
