Don't krill have hard shells? Maybe the little micro-harpoons that anemone use won't "stick" to them very well. I'm guessing here, but it seems reasonable.
I found that I was over feeding my anemone, so now I let a pinch of flake food rehydrate for a few minutes in a glass of tank water until it sinks, and then I suck it up and spot feed the anemone. What the anemone misses is snatched up by the fish, so I feed two for the work of one.
Hey Katy, I just wanted to thank you for starting this thread, and to everyone else for replying and keeping it going! I too am preparing myself to take the octopus plunge and I am so relieved that such an enormous and comprehensive thread like this is going on - I feel like I've learned so much from reading! I look forward to more updates!
Yes! The reason is that water chemistry is much more complex than the simple model that we use to track it. There are many things that we know are important but don't measure for, and probably many other things that are important but we don't know it. Water changes are a way of reset everything, not just the few things we measure, back to a stable state. It's a little like rebooting a Windows computer at least every few days, even if it hasn't crashed. On the other hand, for convenience, you can experiment with waiting a little longer between water changes, based on the good water parameters.
Aha tyvm. I'm supposed to be going on a little trip to Romania on Monday (and tbh I don't actually know if I can be bothered or am well enough even though I paid 400 euro for the tickets). I've tought my neighbour how to feed, check for leaks, replace the evaporated water, check the fish and anemone and test for ammonia. So I want to try and make sure everything is as easy and risk-free as possible while I'm gone.. if I go. I will mix up some saltwater.
1. I wasn't sure if macropus was an appropriate species so I need to do some reading around that
2. My anemone is sick, I am in the process of setting up a 'naughty tank' for George as I've eliminated all other factors, it should be ready by Wednesday
3. My big tank is not octo-proofed at all, I had planned to worry about this later - is it a problem for octopus macropus?
4. I will probably have to borrow money to get it as I'm skint from my holiday
5. The bioload of the tank is almost nothing - 4 crabs, the fish and the anemone - do I need to wait til I have more stuff in there producing ammonia?
