Blood Spot/Blister

[Clairepriest]

One of my White Cloud Mountain Minnows has a large blood blister/blood spot under his chin. I'm treating with Melafix (for last 5 days) but there seems to be no difference. He swims fine and was eating fine (until I quarantined him in a water bottle in the tank. Now he's not, but I think it's coz he's on his own, not coz he's ill).

My water is ok except the acidity is a little high so I'm using 1 teaspoon of pH down per day. Also nitrate is high but I've got loads of plants in there and I'm changing the water weekly to reduce it.

I can't attach a picture coz he's too quick but it literally looks like a little sack of blood under his chin about 1mm big (not big, but looks big on him).

Will the blood blister go? Will he die? Has he just injured himself and will heal like we do? HELP!!!!!

By the sounds of it you don't have an issolation tank, he will need to be treated with a bacteria med, how many gallons is the tank, which fish and what type, i would remove him out of the container as it sounds like it's stressing him out.

Also has the fish been flicking and rubbing on objects.

Your right, I have no isolation tank. He had the blood spot about a day before I isolated him in a container. Do you think if it was contagious the others would have it by now? He is a White Cloud Mountain Minnow and I have 4 others, also 5 no. Garnet Pretty Tetras, 1 no. Pleco, 1 no. Black Ghost Knife Fish, 1 no. Butterfly Fish, 1 no. Corydorus, 1 no. Shrimp and 1 no. Pencil Neon.

The tank is 81 litres. He has not been itching or flicking.

I've been treating with Melafix - is this a bacteria med? If not where and what should I get? I have a Pets At Home Store near me or a specialist fish shop a bit further away. My partner said not to contact a vet but would I need a prescription to get a bacteria med?

Its been a week now and he seems fine, i.e. still eating and swimming around, etc.

I no about small bloodspots and you have to use a internal bacteria med with them.

Can you please post your ammonia and nitrite levels? Also, what exactly is the pH in your water before you adjust it? Have you tested your KH, as that is important to know when talking about the pH. In MOST cases, it is best to leave your pH alone, and let your fish adjust to that pH. The chemicals can lead to swings in your pH, which is very stressful to the fish.

hi

my goldfish have had this problem before.... i've used Interpet no. 9 - anti internal bacteria (can be used wih coldwater and tropical)....and it disapears within a couple of days...(i would continue with the second dose though) you should be able to get it at your Pets at Home, although they arent great with fish they seem to stock all the meds you'll ever need )

hope it works out okay

As you can see from the attached picture:

- Ammonia is normal, i.e. 0 (yellow)
- Nitrate is high around 160 (red)
- Nitrite is normal 0 (light blue)
- pH is 7.4 although it was 8.2



I've attached pictures of my minnow with the blood sack on his chin. Also, I noticed today that 1 of my other minnows and 1 of my tetras seem to look 'yellow' is this anything to worry about/related?



I've bought Interpet No. 9 and administered the first treatment. I'll treat again in 4 days as directed.

Just see if the med work and see if there is any inprovement with the fish, if not after the two courses get back to the board, good luck.

Hi just wanted to add, you meant your tank was slightly ALKALINE, not acid.

Acid is readings under 7.0, alk is over 7.0

Fish can take up to 9.0, but at that rating ammonia is ten times more toxic, so to keep a happy tank it is best to be in the 6.8-7.2 range. Acidic tanks can eat fins up etc, and is more damaging than an alk tank

- pH is 7.4 although it was 8.2

Was this pH a natural drop because you have a low KH or did you alter it with chemicals?

If you are altering it with chemicals, this will eventually lead to more problems, and large pH swings. It is best to just leave it high and let your fish adjust. If your pH naturally dropped over a week from 8.2 to 7.4, it means you have a low KH, or buffering capacity. The key thing with this is to make sure you do smaller water changes so there will be smaller changes in the pH in your tank.

Thanks for all your help. I'll try everything and let you know if they survive. Cheers
