Three weeks ago I introduced a Blue Starfish to my tank along with a pack of Turbo snails.
I have yet to see the starfish so he's either playing extremely hard to get or he's gone to that great big TANK in the sky.
If he did in fact die I have not noticed anything different about my water parameters which I check once a week, with the only exception being yesterday's results:
Ammonia: 0
Nitrite: 0
Nitrate: ~20
Salinity: 1.022
pH: 8.0
Are these animals really that shy (if it is alive)?
Does the nitrate reading (above) warrant a water change? I just did a 15% water change about 10 days ago.
Tanks!
