Rivercats just the person I was hoping to reply. I am amazed by your tank.
I did not make the stocking list myself it was mainly my cousin and had a feeling there were too many dwarf cichlids. He just looks at my 70 planted and sees the pair of GBRs and the pair of Bolivians, his logic was much bigger tank should be able to handle all of them. This is really the beginning of stocking
As for the sae
vs oto I always have Otos and never had issues with them, so of it ain't broke don't fix it.
I like the idea of more angels and the second school of tetras/other small fish. I was giving him my butterfly pleco he has never touched any of my plants.
Thanks for the guidance
