I have a 20 G nano tank for 11 months,The only inhabitant is a tomato clown.And something is chewing her tail.I have no crabs,no hermits,no snails etc.She is in there for 4 months.Please help.
 
Do you have any open powerheads in the system? I had a eel back in the day that would get smaller and smaller (tail) and come to find out it was getting sucked into the powerhead...
 
I have been feeding her frozen bits of fishes,shrimps,dried krills,flakes,boiled egg yolks.She wont eat any algae though.The water quality is a bit rough,nitrate at 20 ppm.Here are two of her pics the pic with full tail is of yesterday and the one with chewed to shreds tail is of today.

No open powerheads.
What I have to do to make sure that it dont get infected and heal properly?
I know that lowering the nitrates ll really help the wound repair.Any other things that ll help heal it faster ?
 
Not sure. I'd say start by checking water params and try to improve them. A series of 10% water changes spread over 3 days or so. Try to feed food soaked in vitamins (selcon or equivalent), and observe for a while and hope for improvement.

If it is caused by a disease, you may need to set up a small hospital tank to treat the fish for a week or two. But first need to diagnose in order to treat properly. IF you don't have a ready/cycled hospital tank, you may want to stick a HOB filter sponge or something in your display tank to seed it with bacteria.. and use that in the hosp tank to start it off. Throw in an ammonia alert badge too for extra protection.

You could also have something hiding in the tank that you haven't yet seen. Such as a predatory crab, but I suspect that is less likely, though possible.
 
I have a sponge hidden in my tank for a qt in need.
She is acting fine like loosing a tail isn't a big thing.I ll tear down the tank soon( changing house!).So what should I look for that can do this ?
And thinking of doing a 50% water change or two 25% water changes.I have also lowered my salinity a bit(from 1.025 to 1.020) as to decrease a bit of stress).There is nothing in the tank other then some macros.
The only critter I noticed is an inch sea slug.
 
Could try some forma green Helps to protect wounds from secondary infections. so It dosent get worse. I'd say def do a few water changes for sure.
 
Yes but I still want to find that what happened to it,bacterias cant eat a tail that fast or like that.The tail was gone in 12 hours!

This pic you posted looks like a fish with no dorsal musculature left.

I think nutrition is your number one problem, possibly followed by bacterial infection, and water quality, as we don't know all of your water parameters.

I would stop feeding egg yolks and flakes today, and buy some frozen preparations for omnivores, PE mysis, and frozen cyclops.

As mentioned above, buy a supplement like Selcon or Zoe/Zoecon. I would *not* consider this optional at this point.

Perform water changes, but make sure to match temp, salinity, and PH exactly. And mix new water for at least 24 hours. 50%, 25%, it doesn't really matter as long as you're improving the water quality. Which also means not using tap water.

If you want to reduce stress, do not change salinity as drastically as you mentioned doing. I would raise it back to around 1.023 slowly over the next week or so.

I would set up a small QT and if there is no improvement in a week or two you may need to treat for a bacterial infection. I'd look up fin rot... causes and treatments.
 
Well the problem is you dont get Selcon or Zoe/Zoecon like vitamin supplements here.I use a mixture of ascorbic acid(vit C) in 100 mg/ml of propylene glycol, garlic juice and vit b comples drop alternatively on food.
I dont think that waiting for antibiotics ll be good.I m also considering anti fungal.
So any antibiotics that should be good ? And antifungal ?
Please refer to generic names so that I can find an equivalent here.
