I have a wide fin zebra Philippine blue (pearlscale). I can tell it is going to look stunning when it's fully grown (don't know the sex yet). I've tried to take a picture of it a number of times, but it just doesn't do it justice...it moves around a lot, and my camera isn't really the best either.
I have others that are stunning as well...a platinum, a marble, and a ghost, all Philippine blues as well, and a non-blue zebra pearlscale. But I think the first one I mentioned is my favorite.
I've always kinda liked the really dark black ones. The greenish ones are nice, too.
My adventures in keeping Indostomus crocodilus, the crocodile toothpick fish. AKA armored stickleback, paradox fish, and freshwater pipefish. Care is (to the best of my knowledge) exactly the same as Indostomus paradoxus.
