I've had this guppy for about a month now and 2 days ago his fins got clamped. I didnt know this wasnt bad so the next day his fins got super clamped. He swims side to side but he still eats and poops normally. He is in a very overcrowded tank. It's a 10 gallon tank with a betta, 4 guppies (including clamped one), 10 neon tetras, 3 amani shrimp, 2 amano sized wild caught shrimp, one yoyo loach, and a common pleco. I'm getting rid of pleco and loach soon so that's some weight off. If anyone has any idea on what can help please help me.

It's probably a protozoan infection. Get a broad spectrum medication that treats bacteria, fungus and protozoans. Make sure it is safe for scaleless fish (catfish, eels and loaches). If you can't find one suitable for scaleless fish, use a normal medication at half strength.

Make sure the medication does not contain copper or it will kill the shrimp.

To work out the volume of water in the tank:
measure length x width x height in cm.
divide by 1000.
= volume in litres.

When you measure the height, measure from the top of the substrate to the top of the water level.

There is a calculator/ converter in the "How To Tips" at the top of this page that will let you convert litres to gallons if you need it.

Remove carbon from the filter before treating or it will absorb the medication and stop it working.

Wipe the inside of the glass down with a clean fish sponge. Do a 75% water change and gravel clean the substrate. Clean the filter if it hasn't been done in the last 2 weeks. However, if the filter is less than 6 weeks old, do not clean it. Make sure any new water is free of chlorine/ chloramine before it is added to the tank.

Increase surface turbulence/ aeration when using medications because they reduce the dissolved oxygen in the water.

Is there a specific medication you reccomend?

Do a 75% water change and gravel clean the substrate each day for the next week and monitor the remaining fish. If any more of them get the same symptoms treat the tank immediately.

I don't recommend specific medications because they vary from country to country. But if you get a broad spectrum medication that treats bacteria, fungus and protozoan infections you should be fine. Just avoid anything with copper in.

Look for a medication containing Malachite Green (treats protozoans), Methylene Blue (treats bacteria and fungus) Formaldehyde/ Formalin (treats bacteria and preserves the chemicals.

If you do have to treat the tank monitor the ammonia and nitrite levels because Methylene Blue wipes out filter bacteria.

Make sure you wash your hands with soapy water after handling the medication or working in the tank. Malachite Green is carcinogenic so handle with care and keep it away from children and animals.

Do daily water changes first tho and only treat the tank if another fish gets sick.
