I recently moved three P. argentius from a much more crowded 165G to a 180G, along with a trio Paraneetroplus regani, and five Thorichthys affinis 'Laguna Sacnab'. The argentius responded to this new setting by pairing and putting down their first spawn. I thought the regani would beat them to it, but that was not to be the case. I am hopeful that they will follow suit shortly.
Here is the pair. The yellow cast is from the light I used.
