Your lovely Bulldog looks like it could be a Chaetostoma L444, just like mine that sadly went missing for three days, only to re-appear dead last Tuesday afternoon. Really gutted, I held out on getting one for months and my 5-foot had what appears to be ideal conditions (moderately hard water, 22C, aeration/current from FX5 and APS2000EF filters). She seemed to come and greet me most times I went down to the garage, dashing over to the front glass, seemingly really enjoying the FX5 current after being in 26C/calm water at the LFS for months (which part of me wonders if this took its toll on her, or is my tank setup not clean enough for these sensitive fish).
What foodstuffs have you seen your one eat? Mine never ate in front of me (which really concerned me), but she regularly pooped, despite offering various things mid-afternoon and just before "lights out" (Tetra Prima, Hikari algae wafers, defrosted daphnia/bloodworm, courgette). Just before she went missing, I had read about "painting" their home rock with food "glued" by egg yolk.
