Parasite Infestations
--------------------------------------------------------------------------------
Description:
Some parasites latch onto the outside of a fish, while others find their way inside. There are different medications and treatments for each so it's important to study and find out what's wrong before treating.
Fish who exhibit listless behavior, rapid breathing, loss of appetite and a thin body like it's wasting away could have internal parasites. Check for lumps under the skin/scales.
Ich is the most commonly known parasite; the fish will have white dots scattered all over it.
Velvet is probably the second most common parasite; the fish will have what looks like a gold dusting of the tiny parasites upon it.
I am not a parasite expert, and there are plenty of other guides out there. So I will list them rather than just trying to re-create a listing here, for more information on the many other parasites out there:

Treatment:
There are a wide variety of products available on the market today. Products containing copper salt, formalin, or malachite green are often effective. But beware that some products like these cannot be used with certain types of fish, such as invertebrates! If you have scaleless fish like catfish, use reduced amounts of medication. It is always a good idea to do some research to be sure your fish type is okay with something before you medicate with it.
Some Mormyrids (elephant noses) may be particularly sensitive and should not be treated with any medication containing malachite green.
The lowering of dissolved oxygen levels in treated water is often associated with the use of formalin or formalin-containing medications.

Prevention:
Quarantine new fish for several days before introducing to any tank and monitor them for any signs of problems. Parasites can only be introduced from other affected fish, whether by fish, water, net, hand, or anything else that may touch the water they're in. Take care to properly sterilize any equipment used on affected fish, including hands!
Internal Parasite Problems:
Some medications are designed to treat internal problems. Another great way to treat these is to feed medicated food to the fish.
Some products designed for this purpose:

Bacterial Infections
--------------------------------------------------------------------------------
Description:
There are a great number of bacterial strains that may affect a fish. Bacteria are present in water at all times. The fish will become susceptible to them when it is weakened by stress or other factors (such as poor water conditions, bullying tankmates, improper temperature or environment, or possibly even injuries), allowing them to take control. Bacterial infections will typically cause the same types of symptoms: lethargic behavior, loss of appetite; sometimes the fish will have red blood-streaked skin and/or fins; can have ulcers/lesions on body, etc.
Treatment:
Because there are a wide variety of bacteria, there are also a wide variety of medications that must be chosen from. Different bacteria are susceptible to different types of antibiotics: some meds work better against gram-positive bacteria while others are more effective against gram-negative bacteria. If you do not know which kind your fish has, you may have luck with a broad-spectrum antibiotic medication that treats both gram-negative and gram-positive bacteria, for example. Most bacteria that infect fish are gram-negative.
--------------------------------------------------------------------------------
Some common Gram negative bacteria include Aeromonas hydrophila, Aeromonas salmonicida, Flavobacterium columnare (which causes columnaris), Vibrio, and Pseudomonas species. Other Gram negative bacteria include coliforms (fecal bacteria) such as E. coli and the cycle bacteria, Nitrosomonas sp. and Nitrobacter sp., septicemia (red streaks in the fish).
Some common Gram positive bacteria include Staphylococcus and Streptococcus.
--------------------------------------------------------------------------------
Prevention:
Antibiotics do not actually cure the problem. Instead they help the fish's immune system to regain control to be able to fight off the infection. Therefore it is very important to examine the fish's environmental factors, water quality, nutrition received, and any other possible stress factors and eliminate these. For prevention, just one important step includes keeping the water very clean by performing frequent water changes. As with any disease the fish is more susceptible to contract an infection following stress. Stress can be caused by environmental factors (bullying fish, improper temperature, drastic changes, etc) as well as poor water conditions.
Internal Bacterial Problems:
Most antibacterial medications treat only external problems. Therefore it is necessary to take stronger measures to get the medication INSIDE the fish: most people do this via medicated food. Another course of action would be to inject the fish with medication but your typical hobbyist is not equiped to do this.
Luckily, some antibiotics are designed to be absorbed internally:

Mardel Labs' Maracyn-Two (for internal gram negative infections only)
Medications
Notes to mention:
Biological filtration systems are not affected by Mardel products.
Please be sure to use all antibiotics properly: do not stop treatment any sooner than 5 days to prevent bacterial mutations, preferrably 7 or more.
Some fish are intolorant of certain medications; research before using. Especially (these are just examples, there are more): scaleless fish like catfish, invertebrates/snails, fry, and don't forget about the plants. Some instances will be noted below, but not all.
Since many antibiotics kill gram-negative bacteria and the biological nitrifying bacteria of an aquarium are also gram-negative, it is better to quarantine the affected fish instead of treating an entire tank.
Simply choosing an antibiotic, unfortunately, isn't enough. Some bacteria are naturally resistant to specific medications, and some are mutated and will only respond to increased doseages. Often it's not possible to even determine what type of bacteria you're dealing with. Or maybe it's both! If the fish doesn't improve within a few days, switch medications. Or try a broad-spectrum one that kills both gram-negative and positive bacteria, such as neomycin, chloramphenicol, nitrofurazone based products, skin absorbed kanamycin sulfate based antibiotics such as Kanacyn/K-Mycin, or tetracycline. Products such as Spectrogram by Aquatronics is an ultra-wide spectrum antibiotic blend of nitrofurazone and kanamycin that's useful for such purposes.
Gram-positive bacteria are often unaffected by tetracycline and streptomycin.
Gram-negative bacteria may be unaffected by ampicillin, penicillin, erythromycin and sulfa
Some bacteria may be unaffected by the usual dose, but are susceptible to a higher dose.
Sulfa based drugs are quite effective against Gram negative bacteria.
