I’m getting my second baby multibar angelfish soon, and I’m a little nervous about how to keep it safe.
My first one was killed by crabs, or at least that’s what I suspect. It was eating, active, and showed no obvious signs of illness. I had seen emerald crabs try to grab it during the day a few times, but it always got away. Then one morning, it didn’t come out for feeding, and I found it dead under the rock where it usually slept, with a pom pom crab already eating it halfway through. That experience made me rethink whether a small 1.5-inch fish is really safe at night, even with inverts that aren’t usually considered fish predators. I could be wrong, though, so I’d love to hear other opinions.
Before adding the new multibar, I removed all the crabs to another tank except hermits and snails. But now I’m also worrying about bristle worms or fireworms, since I’ve read they may have at least some chance of bothering a very small sleeping fish. So I’m mainly looking for advice on what I actually need to worry about, what I’m probably overthinking, and what I should prep before the new multibar arrives.
Thanks in advance!
