Ick In Native Tank, Need Invert-safe Treatment

I have collected a variety of fishes in a 50 gallon aquarium with few plants. I have a large creek chub, 2 creek chubsuckers, 2 juvenile sunfish spp., one juvenile smallmouth bass, blackstripe topminnow, some misquito fish, and shiners. They have started to break out with ick, and some fish show withe spots while many other have no spots but frequently rub on objects in the tank.

My question is, what is the best treatment? However, this treatment must be invertebrate friendly, and i have a variety of freshwater clams, crayfish, and other aquatic nymphs, snails and such. Salt seems to be the best option, but im wondering how well with the inverts tolerate this? Has anyone had experience with ick treatments and clams? The clams took a lot of work to find so i need to preserve them, plus they are large and will foul up the tank bad if they die...

Is this an established tank? How long were the fish in the tank before you noticed spots?

well, i moved the tank to my new home, so i did a full water change, but i did leave the bogwood and sand wet and left all biological means untouched in the filter. Previous to moving the tank it had been established for a few months, no problems ever. After the full water change i let the tank sit unlit for about 3 weeks, then added some native fish i caught. They were all fine for a few days, then i got some feeder shiners at the bait shop, which were also fine. Caught a few more fish, and they were fine. The shiners started to show signs of ick, i assume because they were handled rough and not fed as they are feeders. One juvenile sunfish has a few ick spots (may be damaged tissue), but only the shiners have distinguished spots. Most fish are rubbing up against objects though.

What are your water parameters like? It doesn't sound like the tank is cycled fully.

You also may want to quarantine your fish before adding to general pop. You're going to need a bigger tank soon. Well, maybe not, the smallmouth bass will eat pretty much everything. Then you will need a larger tank.

I'll be honest, after losing some nice blackbanded sunfish a few years ago, I straight to the big guns for ich. (I was trying the salt/temperature thing)

I would recommend that you take the fish out of the tank and put them in "hospital" tanks, then treat them with a standard ich cure. Then raise the temp on your 50-gal so that the cysts go through their lifecycle and die out before returning the fish.
