I've played several rounds with SAE's eating wallichii. At first "no", then
"maybe" and now
without any doubt in my mind a certain "Yes".
They might not "eat" the plant but they bother it enough to actually stop
its good growth. I have the same pattern and have heard the same thing from
others as you just described above. At didn't want to think that they were
capable of this action. "One of my favorite fish cannot be guilty of this
crime!" They were innocent! But after some close spying, they are so guilty!
I have removed them from the Rotala tank and have watched the plants come
Don't add SAE's to R.wallichii tanks as they just are not compatible. The
plants are in a certain area where the SAE's cannot get at them, but some
places they can and the plant always does poorly in the areas were the fish
can get at them.

Does well in general good conditions, well balanced tank etc. No big changes
done to the tank etc. Does seem to do well with snails for a cleaner animal
instead. Snails are about the best cleaners around for fine needled plants
IMO. Add shrimps instead of SAE's and see or try the lowly under appreciated
Gastropods(snails, small ones like pond-football shaped, MTS, and ramshorn)

It certainly does not mind cooler temps. The bio cycles sometimes slow down
at lower temps but the plants should all slow down, not just one plant as
you mentioned. Some plants maybe but not this one. Seemed to do better at
lower temps for me anyhow. It sure likes Flourite and other RFUG substrates.
Your notions were correct about the fish. IF you don't have a BBA problem
etc you certainly don't need SAE's but I love them anyway. Damn nice fish.
