I've got a great little paradise fish called Garfield (because of the orange stripes). He lives in a 5L (1.5G) bow with two plants, one in a pot and one on driftwood. I've since found out this bowl is on the small side, but he was happy enough there. I change 50% of the water once a week, and I've put a pad heater in the bottom of the bowl, which keeps the temperature between 21 and 24 degrees C now that the weather is getting colder here.
I used to feed him betta pellets, but a few weeks ago, he stopped eating them. I bought some frozen bloodworms, which he loved. I also used some Aquamaster Multicure, in case he was sick. So he's been eating bloodworms for the last two weeks. I've since read that they should only be given as treats, as they're not a complete food..
Anyway, on Sunday he stopped eating the bloodworms. I saw that he was trailing some feces, so I tried to give him a chopped-up cooked pea, but he ignored it. He's now been ignoring both bloodworms and pellets for five days. There are no strange growths on him that I can see. I was worried that debris at the bottom of the bowl might be fouling the water, so I washed the whole thing and changed about 80% of the water on Sunday night, adding some Cycle at the same time.
I noticed that when I moved his bowl from his normal quiet spot into the kitchen, with more activity, he perked up a bit. Because of that, I put him next to the TV so he gets something to investigate - he used to be very curious about the world outside his bowl. It hasn't made much difference though. I only got him at Christmas so he can't be very old.
Any ideas for what I could try? I'm going to get an ammonia/nitrate/nitrite test kit on the weekend, but considering I did a big water change on Sunday, I don't think that's the problem. I'm all out of ideas.
Any help would be appreciated!
