10 Gallon Nano Tank

[ekvikmost]

I have a 10 gallon nano tank and I had 3 fish in it until this morning. One baby maroon clown, one small black and white clown and I last Saturday (5 days ago) purchased a very small baby hippo tang. The clowns have been doing VERY well for a few weeks now. I also have a bubble anemone and another anemone (name escapes me) and the anemones are doing great. I also have a tiny green emerald crab to help with the algae problem.
Checked all levels and they are good. Ammonia is good, Nitrite is 0.25, Nitrate is 20 and PH is normal. I cannot get my nitrate under 20 and I realize that my nitrite is a little high.
My hippo tang was doing great and this morning was dead. Temps in the tank are in the high 70's/low 80's. What is going on? It seems anytime I try and add one more fish for a total of 3 (and all the fish are VERY small) a fish dies. I have been told by my fish store that three would be fine, but no more.
Any advice would be appreciated. I do seem to have a small algae issue. Any suggestions on getting rid of algae (I am currently using Al-Gone, which is also supposed to help with nitrates).
Thanks for your suggestions.
Regards,
Karen

In a 10 I wouldnt do more than 2 fish, and get rid of one of your clowns, when they get a little older thier terratorial tendacies will come out and one of then will die, a ten is just way too small for 2 diff clown species, if you still want 2 clowns get the same species and they might mate, NEVR PUT A TANG IN A 10ga!!! EVER!! PERIOD!!! You LFS is just trying to sell you stuff. Do you have any Live Rock? How often are you doing water changes and how much? If you have algea bad, obviously you have too much trate, it comes from over feeding and not enough water changes, with a 10gal you need to be doing a 10% water change at least once a week. And you tanks temp need to stay very stable...maybe a 2 degree change during th entire day, no more, if you cant control it get a better heater or move the tank away from windows and heating/air vents
