Its been a week or so on since we took out the prawn, which went all fluffy! Disgusting! Since then we have added some hermit crabs, 6 blue legged and 2 red legged... I think. I only asked to buy 5 blue legged hermits and some empty shells - I'll let you guess how we ended up with 8 crabs and only one empty shell! We have also bought 2 sandsifting snails and a frilly slug, or lettuce slug as Stu keeps telling me. We also got another bit of Live Rock (about 2kg).
The tank has turned brown with algae and the crabs and snails are kept busy keeping it clean. They're doing a really good job, even if we have helped them with the glass scraper a few times :-) I noticed the glass scraper only works on the side walls of the tank and not the front glass as it it curved. We'll need to find something a bit more flexible to keep it clean and clear.
Stu has taken up the job of top marine chemist and has been regularly testing the water. Our ammonia levels have been a constant clear 0, nitrites rose to 1.5 mg/l and fell within 2 days to 0 mg/l. Our nitrate levels rose slowly to a max of 100 mg/l and are now falling. All good stuff. Time for our first water change I think.
I got a wee video of our hermit crabs when I first put them in the tank. If you watch close you can see one switching shells. How cool is that!
