Yes, I hope they will eat them! All four of them are constantly chowing down, cleaning glass, plants, and driftwood. I'm totally sold on them. I just hope they don't run out of algae, and/or can learn to eat sinking pellets. I already feed these to my Cory cats.
Speaking of these, I have troulbe counting them, but it seems that one may have gone missing.
I bought 5, but can't seem to see all of them at one time. They are excellent at hiding, so I may be just not seeing it. I did a massive tank cleaning/re-scaping/55% water change today, and didn't see a corpse, so hopefully it's my bad.
The work today resulted in a big change of the driftwood position. I found that I liked rainbow fish tanks (like Greggz) that have horizontally oriented driftwood, rather than vertical. I had originally thought that a vertical orientation would serve to make regions for the fish to claim, but since I'm planning a peaceful community now, I don't think I need that.
I also installed new light bulbs on the tank today: again, I'm stuck with my VHO T12s for now, and there's precious little selection of bulb spectra. I did the best I could by ordering Aquasun 10,000K bulbs, and I must say that they are making my reds far more visible than did the aged Actinic 12000K ones that I've had so far. I'm thinking of adding some warm light via strip LEDs, but that's for a different day.
The water change gave me a surprise: my nitrates, which had been running high, were only 20 ppm when I got done. I did vacuum all the substrate (shallowly) and re-position the driftwood, so hopefully there are no festering pockets of waste. I plan to reduce my dosing of EI ferts by about 3/4 for the next week; Burr told me that I've een overdosing, especially micros.
There are pockets of hair algae here and there, and there's some GSA and brown diatomes, but I expected all that, especially since I had so much trouble getting my CO2 under control. It's such a good feeling to finally have control over all major aspects of the tank. Now, to learn to play them like a well-made violin!
Pic below isn't very good, but it gives you an idea.
