Hi I’m Julie I’m new to fish keeping. could someone give me some advice please. I have a 12 litre tank with foam filter a 5 month danio and a 3 month old platy but the last couple of days I’ve noticed the danio struggling to swim up in the water and wondered if maybe he has swim bladder disease- I feed them flakes, bloodworms occasionally and they have had brine shrimp but don’t tend to like it. What can I do to help my young fish as he I struggling. I also have a main 35lire tank with 4 danios and 4 platys. The two in the small tank are what I have rescued from the main tank
5 month danio

Hi and welcome to the forum 
Any chance of a 1 minute video of the fish swimming and maybe a picture of it?
You can upload videos to YouTube, then copy & paste the link here.
If it is a swim bladder problem, there is no cure and euthanising the fish is the best thing.
Swim bladder problems occur in 2 forms.
1) The fish stops swimming and floats to the surface. This is usually caused by air in the intestine and not a swim bladder issue, but it can be caused by a swim bladder issue. If a fish floats to the surface when it stops swimming, stop feeding it dry food for a week and feed it live and frozen foods instead. If it recovers then the issue was air in the intestine. If it doesn't get better after a week without dry food, then it's a swim bladder issue.
2) The fish sinks to the bottom when it stops swimming. This can sometimes be caused by fish eating gravel but that is normally in goldfish and they get a weird shaped belly when they do it. If fish like danios sink to the bottom when they stop swimming, they have a swim bladder problem.

Other video hosting sites are available. But you cant attach a video apart from linking to an external site.

If the fish swims on an angle like it is in the picture, then it has an issue. Euthanasia is the common course for fish that can't swim properly, but post a video first.
