Hi, in the process of planning tankmates for my 4x2x2 planted discus tank and after doing a lot of reading the algae eaters for me seem to come down to BN or Ottos.
As has been mentioned elsewhere in posts, BN can cause a lot of waste even though I do think they do a great job on algae in my tanks. I have 20 5cm BN growing up in a 3 foot tank and the amount of waste isnt a problem as I vaccum it out daily. In a fully planted tank thats not going to be a good option.
I recently read that a lot of Ottos starve in a planted tank due to lack of algae, makes sense once you get the right balance of light and nutrients. I had planned on 6 of these little guys but dont want to get them just to kill them off. I also plan on have 10 C. sterbai so feeding the Ottos algae discs probably wont work as the corys will get to them first.
Any opinions appreciated.
