Hi.I am excited and looking forward to taking your seahorse certification class! I kept a pair or 2 in a cube tank on my desk at a special education Co op way back in about 1998/1999 somewhere in there. The kids and I truly enjoyed watching them very much. I have not had a tank set up in almost 2 decades now. I recently purchased a used 100 gallon acrylic tank which came with a refugium, a canister filter I think,and a stand with a makeshift hood and I believe some led lighting. I haven’t even decided where it is that I want to place the tank yet. So I am open to all suggestions and advice! I can send you a pic of the set up when I get back over to my house probably tomorrow sometime. Thank you, Lesli Ann Maddox DuBois 🐠🐬🐚🐡
