It is 135 gallon tank with a 40gallon sump. It was up and running for several years, but I bought and moved it May 2. We moved 100+ gallons of exisiting water, as well as the live and base rock. It ran for 2 weeks before I installed a protien skimmer (the prev owner did not use one)
I have been replacing 10 gallons of the water weekly (twice the first week) when I vaccum the crushed coral. Mostly my ammonia, nitrites and nitrates are all neg, but I did have some slight nitrite/nitrate levels last week. (.25 and 5). I thought it might be somehow related to the newly installed skimmer, but now I think it was from the dead and rotting cowrie snail I removed on Saturday.
From my introduction post:
I bought/moved an already established predator tank about 3 weeks ago. In it are 2 puffers-- a green stars and stripes (Kiwi), a Valentini puffer (Olivander), a picasso trigger, a white tail trigger, a lion fish and a wolf eel. The previous owner did tell me that Kiwi didn't look so good some times, but that I shouldn't worry about him. But I do worry about him. He looks such a ghastly colour sometimes, and the last few days hasn't eaten much. I have been feeding a variety of seafood, but when he has eaten he seems to mostly like the shrimp or octopus. I read he should have somethign hard to wear down his teeth, so tonight I put in the crabs legs. He seemed a bit interested in that, but the triggers kept going after the same food (even though I spread it out), and he eventually gave up. I am hoping he eats more after they go to bed. Are these fish nocturnal?
I think Kiwi may be intimidated by the other tank inhabitants, but, I'm not sure I'm right (I don't know him well enough) and I have nowhere else to move him even if he is intimidated. My dog, Maverick, is obsessed with Kiwi, I think because he looks like his tennis ball, with wings.
I am going to try and post a picture. If anyone can tell me if he looks normal, and his behaviour is normal, please let me know. Thanks,
What he looks like now:
