Hi there. No emperor tetras here. These are all African tetras. The largest ones are often called Alestes tetra (or African long fin tetra), the ones at the top with blue eyes are lamp-eye Congo tetras, smaller ones at the top left do not have a common name as far as I know. Just Phenacogrammus sp. 'Fantastique', and the large ones at the bottom right are a blue version of cherry red Congo tetras.
@@kmaguire7161 thanks I was actually compiling up a stocking list for my African tank. I’d never seen the lamp eye Congos but now that I have there a must have.
They are pretty dormant at the moment. The plants in this tank are not doing great. The tetras are eating the Anubias and since the tank is overstocked algae has been a big issue.
