Black Moor weird behaviour

[mini.cheddars 0]

Hi, I hope I have posted this in the right place. I have quite a large tank with a baby fantail and a baby black moor. It is mature - I have had them for about 7 months. 

When we first got the Black Moor we thought maybe he was blind or had sight problems because he often bumped into things and couldn't see food like the other fish could. He seemed to rely on smell to eat. He spends a lot of time on his own, in open water just floating with the current or just floating in the cave. Today he is face down against a plant pot. I have attached a video of him. I don't know if he is just a bit strange and lacks drive to actually swim - he eats fine and can swim when he wants to, but just seems very lethargic. Sometimes he tips upside down and floats like this before correcting himself. I've also seen him tip upside down when he gets excited about food. He looks healthy but in the video maybe someone will spot something? 

These are my water paramaters: 

Nitrate 25mg/l (The tank is due a water change) 

Nitrite 0mg/l

GH 18d

KH 15d

PH 8

Chlorine 0

As of the present I can see he's got a swim bladder problem but I do need more information about this set up

I know its very hard. You did good

Now so far looking at everything I can see part of your problem. Goldfish are very very dirty fish. Having an internal filter isn't good for them as it will get dirty faster than you can keep it clean. Plus all that sand and other stuff in the tank is making bad bacterial spots in the tank. I believe is causing an swim batter infection.

 

First thing I would like to see is a HOB filter these are filters that are hung on the back of the filter you will need to have one that goes 10x the amount of water in your tank. So you have a 25 gallon you will need a filter that goes 250 gallons per hour. With 2 fish in the 25 gallon tank I would be doing water changes twice a week. Goldfish need at least 20 gallons per fish to be healthy and happy.

Also I would highly suggest the test that does in in drops the strips aren't accurate at all.  

Plus we really do need the tap water readings too
