I have changed out my 55g tank. It no longer houses coral-moved to the 120g. I have converted it to a seahorse tank. I bought H erectus. I am working on training them to use a feed trough and hitching posts at feeding. They were tank raised so they are able to eat frozen Mysis shrimp but not sure what else to feed them. I am hoping to have little ones at some point-we will see as that is a long way off. These are about three inches in size. I have added tons of artificial flowers for them to use to hitch.
