Space Age contains the Fish breeding recipe, unlocked on Gleba, for a biochamber or chemical plant. Since that exists, this mod has no purpose in Space Age.
Unfortunately, I still need to use this mod in the space age. Because I use https://mods.factorio.com/mod/platformer and https://mods.factorio.com/mod/Constructron-Continued, the former keeps me on the platform forever, and the latter allows me to use spider robots to handle logistics issues. So the question is, how do I get the first fish in space? Therefore, I need your mod.
