That's BBA, all right.
Fish didn't solve my BBA problems. I think for some spotty stuff, not a really serious infestation, the right fish might do pretty handily. I had more than that, and what really solved the problem was a change in tank parameters. I have given up on the silver bullet theory. I think all of us would like a recipe that works every time in every tank, but at this juncture in the hobby, such a thing apparently does not exist. You try this, you try that, and by exercising patience and not giving up, eventually you get the victory. Someone here may give you a tip that works for you. In my low light tank, I trimmed everything out that had BBA on it, did a 4-day blackout, 90% water change, filter clean, removed DIY CO2 and put the lighting up from 1.5 to 2.25wpg. BBA only now shows up in very small amounts on weak and dying leaves that have been left in the tank when they should have been trimmed out. Nothing like what is in your photo, and I had worse than you are showing there.
Tula, I had some Rosies for a short while, they succumbed before I could get a real good feel for how they would do with algae. They are also entirely too large for my small tanks, which limits their practicality IMO. Spanner-Ts get even larger. Are you recommending them as a good fit for BBA control?
