Senior Non-Reef Reef Fish, Help Anyone?

[EmilyB]

Trig is about 6", and Spike is about 5", they are in a 65g in wall. They have been together since I got Spike, through many tanks and disasters....

The system is a bit of a mess, but a good functioning ecosystem for them, there are soft corals, a white urchin that has been there for years, an abalone that is huge and does nightly stuff.

The rock (or maybe so the system) does have aiptasia. Which is why I got the filefish, he keeps it out of the tank, but he needs a covered tank.

I will honestly do the best I can for them.

Thank you for suggesting maintenance, but the tank is at the point of bulb replacement, powerhead upgrade, and potentially a new main pump soon. It's not just a simple water change scenario.
