Thanks. Your info holds good news and bad news for me.
I haven't purchased the fish yet, but just considering my suitability as a keeper.
At least initially, I'm considering a 29 gal species tank or with some added corys. As the fish grow, I'd probably upside to a 40gal breeder.
Matten filter, extra (oversized) internal powerhead for strong current and added aeration, heated to 78F. I wasn't going to cook them because (a) the CLOG says they don't need it and (b) I might add corys. Regardless of pleco species, I've already got several tanks at 85F. I need a couple more tanks at 78-80 to be more suitable for the corys.
Cobblestones, some wood, and clay caves. Coarse gravel in flow, but sand away from current (for corys if present). Tanks will be at work, so I have easy access to DI water if needed. Was planning an approximate 50-50 mix of DI and tap water.
Right now I'm keeping (successfully) several other Orinoco species (B. beggini, He. guahiborum, Hy. debilittera, L201, P. maccus to name a few). But I've also lost every Chaetostoma I've ever kept, none lasting more than a few months (not cooked, they were at 70-75F max in most recent attempts). My worry is the water changes. I try to do 50%-80% WC every two weeks. But life often gets in the way and some tanks will go 3-5 weeks without a water change. That's why I've chosen a Matten filter, they're more stable than HOBs in my experience.
Will that lead me to failure, in your opinion? As much as I'd like to get these, I've learned my lesson with Chaetostoma, and I won't get more rubberlips until I can give them the right setup. Therefore, I won't take on the P. tigris if I'm setting myself (and the fish) for failure.
