I'm in the process of setting up a 20L for a pair of A. viejita Rio Meta that will arrive in a week or so. The cave/decoration information that has already been posted has helped a bunch but I have a few follow-up questions.
Will the fish care if the cave is actually a tunnel with two (or more) openings? I purchased small sections of PVC pipe for the new arrivals. Should they all be positioned against a tank wall or with foliage blocking the back or side opening? I normally maintain a thin layer of substrate. How could I keep the pipes from floating? I thought about wedging pipes at angles in one of the larger castle decorations that are commonly for sale. This would convert the castle into condos. Would that be better received by the fish than several distinct areas? There would have to be two sets of condos since there will be two Rio Metas.
In regards to the "line of sight" blocking that needs to be done- Are we talking about a solid hedge type blockage or a looser Morman Poplar type blockage? Should the blockage be the entire depth of the tank or just blocking the cave fronts so that the fish, if inside, can't see the other cave openings?
Thank you for your time,
Wendy
