Hey all,
Would appreciate any help I could get regarding my poor little betta, Guapito.
Housing
What size is your tank? He was kept in a really small tank until recently. His new tank is 6.6 litres (approx. 1.74 gallons)
What temperature is your tank? I have no idea.
Does your tank have a filter? Yes, his new tank does however the filter is currently not being used as the current it creates is way too strong.
Does your tank have an air stone or other type of aeration? No
Is your tank heated? Yes, the new tank has a heater, however it is currently not being used as it is quite warm where I am.
What tank mates does your betta fish live with? None.
Food
What type of food do you feed your betta fish? Have been feeding him flake food. Was given pellet food when I purchased the new tank, however he cannot seem to swallow them, so went back to flakes.
How often do you feed your betta fish? The flake food packet said feed him three times a day... I thought this was way too much. I have been feeding him once a day.
Maintenance
How often do you perform a water change? When he was in his small tank, every 5-6 days or less if it looked like it needed a clean.
What percentage of the water do you change when you perform a water change? 50%
What type of additives do you add to the water when you perform a water change? The stuff to dechlorinate the water.
Water Parameters:
Have you tested your water? No
Symptoms and Treatment
How has your betta fish's appearance changed? Yes. See pictures before and after. His colour has paled and his fins have completely shrunk/twisted. If observed from above you can see that sometimes he swims with an 'S' shape in his body.
How has your betta fish's behavior changed? Yes. He used to be a real wimp

, now he's quite lethargic and doesn't seem concerned by anything. Doesn't move around a lot. Have noticed that he has not been producing any... waste.
When did you start noticing the symptoms? I got him late December, started noticing the symptoms maybe late January 2011.
Have you started treating your fish? If so, how? Firstly, got him a bigger tank with filter and heater. However, have not been using either for reasons stated above. He does seem happier in the big tank though (I felt the other tank was way too small, even though the store insisted it was fine). Fed him less, fasted him for 24 hours. Tried giving him a bit of the inside of a pea.
Does your fish have any history of being ill? Nope.
How old is your fish (approximately)? Got him from the store just before Christmas 2010. So I have had him for less than 2 months; not sure how old he actually is though.
Before
After (the picture kind of distorts his head haha, his head is fine! just note the fins)
both pictures taken in old tank, by the way. new one is big and very pretty :)
So yeah any advice as to how to get guapito happy and healthy again would be appreciated. I have tried googling for advice (constipation etc.) but there's just so much information and it's hard to get through. Would also appreciate advice regarding the filter and ways to slow the current down? I have only put it on once for less than a minute, he definitely did not enjoy the experience.
thanks again
