I was just at a Rain Forest Cafe today, and sat next to one of their tanks, and the same thought that always occurs to me occurred to me again, don't they know anything about marine fish?
When they first opened up here in Chicago, the store that stocked their tank gave them over 300 fish at the same time (I won't incriminate Living Sea in Park Ridge by mentioning their name) that were very very large (needless to say, not a single one of them was alive within 2 months time). Even then, I knew that they were either ignorant, or stupid, or possibly a combination of both.
Ever since then, every time I go back (I know, don't patronize them if you don't agree with them, but my daughter enjoys the rainstorms and the moving animals) I am appalled at the conditions in their tanks.
Beef #1 - General Health
Their fish always seem to have some sort of parasite or virus or disease of some sort. Every tang and angel is always flaring its gills at the current, and that suggests some sort of parasite on their gills to me. Visible ich and lumps over the bodies of the fish also is rampant.
Beef #2 - Water Quality
Ever notice the slime algae covering everything? It's pretty gross when the bright decorations are all covered up, and to top it off, you wouldn't be able to see that some of the decorations are yellow anyway, since the water is too.
Beef #3 - Compatibility
In one tank I saw today (granted it was pretty large, probably 4'Hx6'Wx2'D, but probably over 50% of the swimming area was taken up by 2 large decorations covering the filter area) they had a large gray angel with a clouded over and popped eye also in the late stages of popeye, a large french angel that sat with its head in the coral the entire time, a juvenile majestic angel finishing up its color change, a medium sized blue face angel, large domino damsels that were completely discolored, a hog fish, a porcupine puffer, a cuban hog, a large batfish, a large sergeant major damsel, a large jewel damsel, a hawkfish, and some other fish as well that were too busy swimming into the wall to come to my side of the tank. Now I will mix angels, and often as well, but not in those conditions with them obviously picking on each other. In another tank, they had (and the tang lovers will go ape over this one) a mixture of pacific blues, atlantic blues, sailfins, yellows, and probably some more as well. Mixed in there with them was a huge panther grouper, a bunch of batfish, other miscellaneous groupers, and a bunch of other miscellaneous fish. Again, HUGE cylindrical tanks joined by a swim through area, but also again, huge decorations taking up over 50% of the tank volume.
Beef #4 - Recreation of a Natural Environment
For a chain that says that it wants to maintain the integrity of the worlds rain forests and keep them pristine and unchanged by human development and interference, they sure don't know jack about fish. Going back to my above example, how are you portraying a natural setting when you have a mix of an atlantic blue tang and a pacific blue tang in the same tank? You're either in one ocean or the other, not both. Not that I don't mix and match in my system, but if your goal is to replicate nature, how do you mix oceans?
Just wanted to air my opinions, as I have aired them to the managers probably half the times I've been there (it usually starts with "your fish died as I sat there at the table, my guess is you need to....") and been ignored.
