Exploring the world of caves

[Flipside]

Hi, just a quick question about caves in my tank. I've got pea puffers and Otocinclus catfish on the way for my 10 gallon planted setup. What's better for them - a cave with an entrance and exit, or a one-way hideout? I also wondered if I should have a cave for each fish, so they all have their own little home. Thanks for your input. My boyfriend says I overthink this stuff... but I just want my fish to be happy.

I think it's better to have more than one way in and out so that a fish doesn't get trapped by an aggressor, that way they can just swim out the other side if they feel threatened.

In my opinion, having interesting rock formations would be the key. This allows them to graze on algae and also provides a sense of security and visual interest. I'm not sure they necessarily claim a specific cave as their own, it's more about having a variety of hideaways and visual barriers to explore.

I was advised for my Mbuna tank setup that a tunnel with both ends open would be useful for a fish to escape from a chaser. On the other hand, a cave might be more beneficial for breeding purposes, as they tend to defend it. I'm not sure about the accuracy of this theory yet, since the tank isn't set up.

Several people have pointed out the importance of line of sight. Apparently, if the aggressor loses sight of the other fish, it'll stop chasing.

I truly believe that having fun with the aquascape is key. Don't just toss in some decorations and call it a day. When you put thought into creating a beautiful environment, it makes the tank more enjoyable for both you and your fish.

That's a good way to think about it - just keeping things interesting for them. I've found that when I create an environment that's visually appealing, my fish seem to thrive. Providing a variety of rock shapes and surfaces for them to explore can make a big difference in their overall happiness and well-being.

I've found these amazing coconut shells that make perfect caves. Cut them in half, add a couple of holes with a hole saw, and you've got these adorable little igloos. I'm pretty sure the organic aspect of coconut shells is beneficial for the water quality too.
