There are two possibilities
Tail biting only in bettas
Symptoms
- ripped fins with no black edging
-constantly in a "C" shape as of trying to bite the tail
Treatments
Since sometimes tilting isn't stress related and it's because if genetics and heavy finnagge it cant always be treated. For bettas that have it as a result of stress or insecurity, in large tas with no cover tailbiting is very common
-adding more cover
-adding more stimulation.
-keeping Betta in a low or high traffic area
-providing optimal requirements
-changing a decoration during water changes for a new habitat
Cause
This can be caused by stress, insecurity, or heavy finnagge, two of which can be successfully treated. The other can be hard to treat as its a result of naturally genetics and heavy finnagge
Prevention
As long as you provide the optimal requirements for bettas they should have no Stress and no desire to tailbite. tailbiting is very uncommon In plakat bettas.
Fin Rot Information
Symptoms
-Ripped tails, bloodshot, black edged, or has a fuzzy white appearance in the edge
-The fish will become unusually inactive
-Won't eat
-Looks pale, and loses lots of color
Causes
This prolific disease is caused by stressful water conditions primarily but here are a few main examples of the conditions it is most likely found in
-Poor water quality with unacceptable amounts of ammonia, along with nitrites and nitrates
-Nippy tankmates
-Incompatible tankmates
-Tailbiting
-Plastic plants ripping fins constantly
-Over feeding
-Over crowding
-Sometimes after a disease, while the bettas immune system is low it can strike unexpectedly
Treatment
This disease is most commonly treated with mainly
-daily water changes of around 25-50 so more diseases dont settle in while the Betta is vulnerable
-a high quality fin rot treatment. Use tetracycline or Ampicillin for the best possible results
Prevention
-Keep the water clean
-don't over feed
-choose the right tankmates
-make sure that the bettas fins are always in the best shape
-keep the water heated
-change the water as needed
Damages to body or fins
If Part of its fin, or body is damagesd then precautions should be taken to healing it
I would recommend slightly rasining the temperature within the tank to around 80-82 degrees Fahrenheit as In My Epxerience injuries and rips in fins heal faster with higher temperatures. Only if you have fish that are tolerant of these temperatures though should this work.
Adding a small proper amount of aquarium salt if you have plants and fish that are tolerant of it, before adding a treatment of aquarium salt to your water always ask if the plants or inhabitants you have are tolerant of salt, hornwort, scaleless fish, tetras, and catfish a mostly intolerant of salt, it impacts them greatly
Keeping the water very clean and maintaining pristine water quality within the tank, depending on the size of the tank, the stocking, plants, and the filteration. I would usually recommend daily small water changes to keep ammonia minimal and to prevent diseases from occurring on the fish, fin rot is most likely to occur where there are rips in the fins. Fungal diseases are very common in fish with injuries to the body
Keep stress minimal, ideally if there are rips in the fins, you would want to take extra precautions to keep stress minimal, keep flow minimal, provide extra cover, keep area dark and warm. Dont bother the fish that much, a stressed fish has a lower immune system which leaves the fish by susceptible to many stress related diseases, such as fin rot, fungus, velvet, ich, and others that are related to stress but not considered diseases, such as tailbiting
The first sign if healing and new growth forming would be transeculant/clear edges of the fins occurring, or new scales growing back in most fish.
