I've found a much better way. Everyone says to use peepers, but breeding them requires taking up possible space for an extra room because you have to build an entire multipurpose room with a containment unit, and then wait for all the peepers to breed till you have a good enough energy source.

Instead, by only using about 1-2 titanium, build a single plant bed in the same room as a bio-reactor and plant a lantern fruit to grow a lantern tree. You only need to place 4 in to fill the reactor completely, and it is much more space/resource efficient and reduces the hassle of having to constantly run into the other room and removing a bunch of peepers from the tank to fill up the reactor. Just a few clicks and button presses and it's filled again. This way, you'll also have space to build another room for something else.
