As an MD married to a DVM let me chime in a little about antibiotics here as i think there is a lot of anecdotal evidence out there with little understanding of the actual science. As aquarists, 99.9% of the time we are treating infections empirically - we have no clue what we are treating as few of us have the resources to send a specimen to a lab to get a correct ID. Ciprofloxacin is a broad spectrum antibiotic with good coverage of gram positive and negative bacteria. It is particularly effective against ciliated bacteria like Vibrio that are frequently cited as marine pathogens (see whole thread on treating host anemones with Cipro in the anemone forum). It binds to an enzyme unique to bacteria that essentially keeps them from using their DNA for any purpose including replication. It is bacteriocidal unlike the macrolide antibiotics (erythromycin) which are bacteriostatic (keeps them from replicating). Macrolides are also very broad spectrum and do cover some atypical species of bacteria that might not be covered by Cipro. Sulfa drugs like trimethoprim/sulfamethoxazole have a similar spectrum of coverage to the fluoroquinolones (Cipro, enrofloxacin,...) but work by poisoning bacterial synthesis of folate which they require for reproduction of their DNA.
If you do not feel the Cipro is working, I highly doubt changing to another class of antibiotics with a similar spectrum is going to make much of a difference. You might consider adding a second agent rather than switching from one to another, but it makes me nervous to be treating one fish with so many medications. If you feel the Cipro is having some effect, you might consider increasing the dose - it is possible your dose is just at/below the threshold necessary to have an effect. Observe the fish after you increase the dose so that you can get it out if it appears to be having some toxic effect- don't make the mistake of doing it before bed. The listed dose for most fish antibiotics is extrapolated from human/small animal dosing and a good measure of trial and error. Different animals eliminate/metabolize meds at different rates. I doubt, other than for food fish, that the elimination/metabolization rates for fish have been studied so the correct dose is really just an educated guess.
Metronidazole has a completely different mechanism of action and covers mostly anaerobic bacteria and some protozoa. Might get you something the other meds aren't giving you.
Was Rufus able to give you some pointers on how to treat the fish? It seemed from his earlier post that he had a magic bullet for this issue.
my bandit(avatar) ate mysis, seaweed and pellet since the very first day
weeks later he ignored mysis and seaweed, only ate pellets
weeks later he starts to accept seaweed again
and now coming 6 months old, he still refuse mysis shrimp
i saw him pecking on sponges too

Just took that tonight. If you look at the head, that is wear it has ruptured and moving from that point toward the back, you can see the new lump. Under the fin, you can see the infection which looks like it is getting better.
Ive never gotten around registering myself on rc till I started following this thread.
The reason being that my bandit has the same issues as yours. It started with a small reddish lump on it's flank which went away after a few weeks. Recently, another lump has appeared at the base of the pelvic fins much like yours. Additionally, another bigger reddish lump has appeared at the base of the pectoral fins as well.
Coincidentally, I noticed it started developing when I dosed prazi. Correlation or causation im not too sure. Maybe the flukes dropping off caused it. Maybe it was already developing under the skin even before that and it wasnt just noticeable to the naked eye.
Nonetheless, when the reddish lump on its flank appeared, I simply maintained good water quality and let it heal on its own. Sure I freaked out but the fish was swimming and eating well.
Now its been a few weeks since the two red lumps started appearing but its still chowing down mysis, seaweed and nls pellets with gusto. I am tempted to catch it out for a paraguard bath but I would let it heal again by itself unless more lumps starts to appear.
I realise bandits are really water quality sensitive. A slight change in parameters, you can really see its unhappiness. As for your bandit not eating, I would stick out my neck to say it has went through too many medications as you noted. I would say if you're at your wits end and the condition of the bandit doesn't improve in the coming weeks, pull out the medication. Let it get "clean" water. Better for it to be eating and receiving nutrition rather than the lumps healing but it's slowly wasting away.
Best of luck man.
I would never take a Bandit over 4.5", they definitely have a difficult time adjusting to captive fed meals like mysis, brine, etc. Ideal range is 2-3" if you don't want the hassle of feeding a tiny juvenile every 2 hours. When I first started keeping Bandits, Rob Lower (RIP) would send me fish that were 4.5-5" and would take days to eat anything. He sent me three at that size and only 1 survived longterm. Matt sent me a 2.5 and a 3" Bandits that were pristine and ate right out of the bag. Back in 2009, I paid $900 for the pair!!!
Here are some current prices on Bandits based on size ( or at least what I have been quoted over the last 6 months):
Juvi- $1200-$1400 each
2"-3" $900-$1000
3"-4"- $800-$900
4"-5"+ -$600-$800
