Hello everyone, I am not new to aquatics but am new to salt. I have kept fish almost 30 years and I have 15 aquariums , a koi pond and also a goldfish pond. I have two younger children ages 5 and 7 who are wanting seahorses and starfish. I have a 14 gallon that I thought about changing over to a dwarf seahorse tank.Any help you can offer I am all ears.
