Sorry, we got a little side-tracked. It was all in the name of fun....What happened to this topic?
Anyway, I'm extra peeved at the albino pleco at this point. Looked at the tank today and not only has he kept digging under the dragon stone and completely ignored the new log ever since I put it in, but over the course of last night he managed to uproot nearly all of my best-growing section of ludwigia despite it not being too terribly close to the digging spot.
Moved the rock around a bit, filled in the hole, replanted the ludwigia farther away and repositioned some of the driftwood nearby so it fits into everything better. Got the pleco to scoot into the log cave just so he knows where it is, except I came back a minute later and he was back on the tilted piece of driftwood where he sits before going back to his digging. Uuuuugggghhh...
I'm this close to just rehoming the thing.
It's kind of a pain, but I quite often use cork rounds in my tanks. I cut or rough up the edges a bit so that the cut ends aren't so even and they look more natural.
The pros: they're natural, my badis love to spawn in them (I'm sure other small cave spawners would like them too), mosses, java fern and anubias attach to them well, they come in different sizes and shapes to accommodate all kinds of fish that like shelters, and plecos (including BNs) love them.
The cons: they take forever to become water-logged enough to sink and have to be weighted down, and plecos (including BNs) love them.
Discussing the pros:
1. Most are self-explanatory.
2. Plecos love them. They love to hide in them and enjoy having a source of wood to gnaw away at right in their hideaway. The shape of the round keeps plecos from digging up areas under rocks or around driftwood to build a hideaway they're comfortable in.
To address the cons:
1. Weighing them down can be a major pain. I've created some cool structures out of rocks, cork rounds and drift wood that look like an old mass of roots and rocks along a shore, and I've used rocks to weigh them down from behind where the rocks are hidden behind plants and or driftwood and can't be seen. Finally I've weighed them down with slate by drilling a couple of holes in the bottom of the round front and back, drilling holes in a piece of slate (slate tile is cheap, slate is easy to drill, and easy to cut with a coping saw as long as you keep it wet so it doesn't overheat the bit or blade), and then looping cut-to-length plastic coated twister seals through the round to the slate, tying the two ends underneath the slate. Anyways, getting them to stay sunk is a little work but I love the end results.
2: Plecos love them. They love to hide in them and enjoy having a source of wood to gnaw away at right in their hideaway. That gnawing can wear down the round pretty quickly and before long it's more of a cork sieve than a cork round. That really sucks if you've managed to get good plant growth established on that cork round or if you've used the round as part of a more elaborate decorating scheme.
