Wish my experience was a good one but unfortunately is not . I purchased an Ora pygmy file fish from live aquaria 14 months ago and he is as cool of a fish and very unique .
After the tank hit the 1 year mark I wanted to delve into corals and all the colors . So I order several zoas ,a zenia, Gsp , cyphastria, birdsnest and pavona( easier beginner corals ) . Once i got my parameters to the corals liking they began to take off.
I went out of town for 3 days ( and left the feeding and tank care to the family,,,made up premixed feedings so i know all the feedings would be as I do ) when i got home first thing I noticed is the GSP was totally wiped out,,,gone,,, and any zoa with bright green on it had the bright green eaten....im affraid Dave the file fish ( and family favorite ) is the culprit. Its a 75 gallon tank. It has 2 clowns , 3 pj cardinals, 1 yellow tail blenny, 2 yellow gobys , and Dave the file fish.We also have a urchin and turbo snails and a couple scarlet hermits. So I thought at first possible hermit but the GSP was on a magnetic rack on the back wall of tank and totally inaccessable by the hermits. That pretty much leaves only Dave.
Another interesting thing is that Dave over the last couple weeks went from model citizen to a jerk to the PJs . Im thinking because the Pjs have similiar body shapes to the file fish . Maybe its a spring time mating thing but hes constantly chasing and flashing and changing patterns ( which is cool to see the color change ,flashing)
So now im at crossroad ,,do I just settle for a fish only tank,,,,or rehome dave and get the corals and colors in the tank i really want... Or make a smaller tank for bad boys like Dave....
Your experience may vary,,,but mine went sideways as Dave matured. And hes definetly not zoa, Gsp safe.
