I have a 600ltr reef tank and a 300ltr tank I have just changed from reef to seahorse. This week they had a bacterial infection and I lost 3 ponies, I am heartbroken. the remaining ones are in a holding tank, I have totally emptied my 300ltr, scrubbed it out and the sump, refilled with 100ltrs from my other reef tank and 200ltrs nsw. I have added live rock and will cycle for a week before putting the ponies back in with a sand free base, little live rock and some plastic hitching posts. I am determined they will not get ill again, I feel so guilty they passed away because I didn’t know how to care for them properly. the only exotic vet I could find was on holiday all week, I think if I had access to antibiotics they may have got better, so I have now registered with an exotic vet and have ordered furon 2 from America and managed to get hold of some iodine, which took a week to arrive. I really want to learn all about these amazing creatures and cant wait to start!
