Okay, so I've had my tank a good 2 months now and after a week or so after I had set up the tank, [i tested the water and it looked good] so I added 2 clown fish in. They did absolutely great and just last week, I performed a 25% water change so I could get new water in and I did everything I was instructed to.
Few days later I tested out the salinity and all the pH levels, the nitrates, ect...and they were great! No complaints and my fish seemed happier than ever.
Okay, so that was about 9 days ago and friday I introduced an emerald crab to the tank to fight off some of the bubble algae in the tank and he adapted quite nicely. The fish didn't bother him but they took note after is acclimation that he was indeed present.
Anyways, the past 2-3 days now, my clown fish have seemed very un-intrested in food and have been kinda, mopey to describe in the best words.
All the chemical levels are great except that I noted the nitrites went up slightly, but under the tester strips it still said that it was 'okay' but not 'favorable'.
I do feed the fish a pinch 2-3 times a day, very well spaced out. There isn't any ick on them and nothing out of the ordinary except their moody behavior, and the slight elevation of the nitrites in the tank. I added some "Prime" to the water because it stated on the bottle if there were any odd levels of Nitrite or Nitrates in the water after a water change to add some directly to the tank and let the filter do the rest that it should bring balance back to the water. After a few hours I noted the fish did indeed start swimming around more but kinda went back to their little haven next to the live rock in the tank where they normally 'sleep' by after the lights go out. They also will pick at food on the bottom of the tank from time to time, too.
Okay, after all of that I have concluded of the following:
I need a new filter...as I have rinsed it 3-4 times and haven't replaced it yet after the first 2 months.
I'm over feeding the fish?
Or, they are unhappy with the crab on their rock.
Does this sound like it could be one of the following or do I need to run out and get more supplies to do a water change again [yay, especially since I'm at 9 months pregnant right now, lol belly in the way] or should I wait a few days without feeding them to see what's up? I'm planning on getting a new filter this weekend with payday on friday, but I need opinions because I'm pretty attached to these little guys
Thanks SO much in advanced.
