Hi - I've kept goldfish for around 10 years, and recently I decided to try my hand at looking after another kind of fish. With some advice online at another fish forum, I decided to get a betta. I bought him around 4 days ago and he's become quite lethargic - I'm wondering if you can help me.
What size is your tank? 25 litres
What temperature is your tank? 27C/80F
Does your tank have a filter? Yes, an Interpet internal mini filter
Does your tank have an air stone or other type of aeration? No
Is your tank heated? Yes, to 27C with a Fluval E50
What tank mates does your betta fish live with? None
What type of food do you feed your betta fish? Hikari Betta Bio gold, and I tried him with some freeze dried bloodworms today.
How often do you feed your betta fish? Twice a day, 2 pellets at each meal
How often do you perform a water change? It's a newly set up tank (I seeded the filter with media from my healthy goldfish tank) and I've been changing water as often as my test results say - about every other day. I plan to reduce that to once a week once everything's settled.
What percentage of the water do you change when you perform a water change? About 40%
What type of additives do you add to the water when you perform a water change? Interpet tap safe and I've been using Nutrafin Cycle in an attempt to boost the filter.
Have you tested your water? If so, what are the following parameters?
Nitrate: 20 (I changed the water after this test)
Symptoms and Treatment
How has your betta fish's appearance changed? No
How has your betta fish's behavior changed? He started off quite active, swimming around the whole tank. Now he's really quiet and lethargic, spending most of his time hiding in a plant, coming up occaisionally for air and food.
When did you start noticing the symptoms? Yesterday
Have you started treating your fish? If so, how? No, because I don't know what's wrong.
Does your fish have any history of being ill? No, but I've only had him a few days.
How old is your fish (approximately)? The fish store I got him from said they'd had him for about 4 weeks, I don't know how old he is though. He's about an inch long.
I'm totally new to bettas and I'm still learning what's normal and what's not. The first 2 days I had him he was quite active - swimming backwards and forwards, eating well, and sleeping at night. The past 2 days he's been quite inactive as I described above.
I've been having problems with my tap water - at the moment it reads 0.1 for nitrites and 10 for nitrates. Bit of a pain with a new tank! My goldfish tank has a strong cycle and lots of live plants so can deal with it, but it's a bit trickier in the betta tank. The nitrites got to 0.2 one day, and the nitrates have been at 20. Changing water has obviously been a tricky business what with the tap water's readings. Since friday the nitrites in the tank have been 0. I guess the nitrates built up to 20 so quickly because of the nitrates already in the tap, along with the nitrites which then become nitrates.. I'll keep changing water to lower the nitrates each day, but don't want to overdo it and end up putting too much nitrite in the tank for the new cycle to deal with yet. I've also got 2 live plants (anubias) which should help in time..
Rupert (my betta) looks physically ok - no unusual findings on him, it's just his inactive behaviour that's bothering me. Also - I've noticed his poop (at least I think it's poop - not wishing to be rude but does it come out further forward than you'd find on a goldfish?) looks a little pale and stringy. I don't know if this could be a parasite thing, or a stress thing because of finding himself in a new environment, along with the water issues I've been having.
Here's a picture of his tank?

I don't know if this is normal or if there's anything I can do to help him.. please help! :(
