Nice to see another big Distichodus Sexfasciatus.
And nice to see yours is also quite red. I have one also.
They're not strictly vegetarians.
Besides algae mine eats morioworms and the little frozen
fish I feed to the Bichirs. And any green pellet or mysis which sinks off.
Nice setup you've got there! Your Distichodus has all the algae he wants. No need to worrie bout spirulina or other greenish stuff.
When all the wood's clean, you might consider feeding some (protein containing) pellets.
You have one Distichodus?
I believe mine is on my gallery.
And bloodworms are low in nutritional value, I noticed mine does not like it either, but he likes mysis tho.
