I have been looking at fish to add to my seahorse tank for some time now. This will be the first saltwater fish I've ever bought besides the horses. I have my QT tank all ready to go, I just need the fish. I am looking for something small, my tank is 47 gal and skinny & tall, something that doesn't hide all day, and is reef safe. This is mainly for my 14 mo old son as he loves fish but I doubt he even notices the horses . That's why I am looking for something that doesn't spend all day hiding. So far I'm interested in blue-eyed cardinals, possibly getting 3, or maybe one PJ cardinal and a goby that stays low in the tank. Any thoughts on these? Bangaii cardinals are neat too. My tank is about 1/2 uncovered so a firefish or dartfish wouldn't work, though I like those too. I've researched several of these fish, but any site that is selling them all seem to make them sound so easy and great for any conditions, so personal experience would be great here! I have great water params, my tank's been running for almost 3yrs, my main rock is a large holey rock with lots of hiding places, and I can handle feeding any common food. The horses get mysis a couple times a day already. Feel free to mention any fish you think would be colorful and fit the requirements that I might not know about.
Thanks!
