I have some of them
- 3 SAE ... oh how they love beef heart mix, maybe just for a desert they taste a little bit of algae. Where young they were super effective. Maybe I should change it for a younger model
- ~20 Amano, once I even tried to breed them, but failed at some stage.
- 40 RCS I added to tank two months ago ... but who knows how many I have now. Haven’t seen them for a while. Occasionally catch some from a sump. I’m not sure how many are there now. So you’re saying it’s not really fair fight. Either they it algea first, or will be eaten by discus.
Oto? I hear they are not a good company for discus as they might attach to their slime
