I think I should try some of those pellets as well
No more angels to steal my kuhlii's food anymore.
Maybe a tip:
Feed them trough a plastic tube, this way you can place the wafer axactly where you want them, even under the cave.
this way the angels can't get to them.
I use 16" curved hemostats to place food under the cave (the angels see them and attack like rabid wolves), but as they eat, the kuhlis and frogs often poke food back outside the shelf.
And I saw one of the biggest angelfish wriggle SIDEWAYS in UNDERNEATH that shelf (which is barely half an inch off the tank floor, and half an inch from the walls) to get a bite. We both thought he was stuck there, for a few seconds.
And some people think going to work isn't exciting.
Do kuhlis develop patterns like yours as they get older, or are they born with the same patterns they have through their lives? Mine pretty much just have triangles draped over their backs with a one or two light dots on their spines.
There's about half an inch between the shelf and tank walls, front, back and side in an effort to discourage the greedy angelfish. It sits up on four bottle caps filled with sand.
But it's only ten inches long, so they want another one for the other side of the tank.
None of my kuhlis have ever altered their stripe pattern shape or shade.
