Looking for a couple of large hides for knife fish/eels/ loaches and the like and they have some interesting stuff in their reptile section, is it aquarium safe ? Its the same plastic as the fish decorations and they say its the same company my concerns the paint.
You could try bamboo pipes. They sink easily with a boil and knife-fish love them. A lot of knife fish will also hide in clear tubes because they're using electrical sensations to determine if they're sheltered, not the type of "vision" we use.
