Tank became unlevel over time

[cannedham]

Right before my most recent water change, I noticed that the water level was a bit uneven (back of tank is higher than front of tank). The pictures are attached.

My question is: does this look like something I need to address immediately. I don't have many options as I am on a 3rd floor apartment, so any modification to the floor or "real estate" (move the tank somewhere else) will not be feasible.

Just buy some shims and shimmy where it is needed to be level again

I'd call that level. I wouldn't bother with shims or anything and check it again in 6 months.

I agree with this.

That looks pretty good to me. Keep an eye on it. How about you share more pictures of that nice little green terror

At some point in the future you decide to shim it up, use plastic composite shims.
