Hi, I'm new to your forum. I've had an aquarium set up in my classroom for the last 10 years.... just retired & brought it home with me. I had 3 fish and a sea urchin - the youngest is @5yrs. old... didn't have the heart to give them away.... my fire clownfish is such a stinker I'm afraid anyone but me might flush him! Since I actually have time to give them the attention they deserve I will be asking for lots of advice.
