(SBD) The swim bladder is present in most fish, and is used to keep the fish upright when swimming, and helps them go up and down in the water. Problems can be caused with the swim bladder by over feeding, constipation or an internal infection. Fancy Goldfish and Fancy Betta splendens are prone to this. Symptoms are often teamed with bloating of the stomach area.

The best way to treat a swim bladder problem is to catch it early, if you notice your fish unable to right itself, starve it for one day. Don’t worry, fish can go for a surprising length of time without eating. On day 2 feed him with a little cooked de-shelled pea. This acts as a fish laxative. Starve for another day or two. Watch for any improvement.

If you notice any other symptoms it may be more than over-feeding and be an internal parasite or infection. Other symptoms that would hint at this would be a sunken stomach, not eating and hiding in the tank. In this case you will need to isolate the fish and try and treat with Anti-Internal Bacteria medications. But if the fish has gotten that far along it may be too late. Internal infections are notoriously hard to treat in fish.

It often shows itself as a white cottony growth on fins and should be treated as soon as spotted to minimize fin damage. Bettas are particularly prone to fungal infections and adding Aquarisol to their water every other week is worthy of consideration if they are kept in a bowl or other small tank.

Providing an environment that is noisy, sparse or ever changing (ie reflections, moving ornaments, etc.) will alarm the animal and raise its metabolic rate so that it gets a reduced immune system and therefore more prone to catching diseases.

Allowing the levels of ammonia, nitrite or even nitrate to rise beyond their usual low limits will cause damage to the aquatic animal. Reduce these levels by performing regular water changes to get the levels down and examine why they were high in the first place and correct them so they don’t happen again.

The most important thing to do to reduce bullying is to ensure that you have compatible tank mates and your fish are being kept according to species guidelines. For example, two male bettas cannot be tank-mates no matter how big the tank. There should be one hide or leafy plant per fish in aggressive or semi-aggressive tanks. There should also be enough room for each fish to claim their own territory.

Semi-aggressive and aggressive fish should not be kept in anything smaller than a 76 Litres (20 US G.) unless it is just a single small fish. Bullied fish will often have fins shredded or scales missing. They should be removed and watched for bacterial or fungal infections. If you don’t have an extra tank a temporary divider should work. In fish that establish hierarchies some fighting will occur whenever a new fish is added. The decorations should be rearranged and at least one added to give the new fish some place to seek refuge and leave everybody to re-establish new territories instead of defending old ones.

• Note some fish like Tiger Barbs practise status position in their shoal by using their mouths and body orientation to dominate another of the same species without doing harm. However if kept in groups of less than 4 or 5 the Barb will out of frustration try to dominate other species which may lead to harm as the other fish doesn’t respond by performing a submission role and is therefore repeatedly ‘attacked’ or nipped.

No one food contains all the required protein, vitamins, amino acids, trace elements. So feed different foods. Bits of raw fish flesh like tilapia, tuna or salmon fillets are very good alternatives to simply feeding flake or pellets. Raw or frozen foods can contain parasites though. Adding conditioning salts to the tank helps to keep parasites down.
