So we have had our fish for just over a week.
I don't want a flaming because we got them before I came onto this part of mumsnet and I have realised that so many things were wrong with it!
We have a 19l tank, with two little fish. A 'small' (or so pets at home says) oranda and a Blackmoor. I have a filter that is on all the time, and an air pump I put on a few hours fo the day.
I cannot lie that I have fallen in love with the blackmoor.
But this morning I have come in and he looks almost dead.
He has no energy to swim and was stuck to the filter.
I turn the filter off and he just floats around at the top of the tank, he is still breathing but by th elooks of it it won't be long 
Is there anything I can do?
What do I do if he dies?
The other fish seems absolutely fine but has always been more active than the Blackmoor, who often just hides in the ornaments.
Yesterday the Blackmoor got stuck in one of the ornaments, we have a bubble blowing starfish thing? It had fallen over, he swam inside it and got stuck.
We got home from work and college and thought he had disappeared, Luckily I saw his tail and we managed to get him out.
Yes, Pets at Home are shocking and they have a 2 week guarantee or something but I can't see myself going back in there and getting another one if he dies.
Sorry this is all over the place, I am worried.
I can't believe I am so attached to one fish after a week and a half!
I didn't even think I liked fish.
Help? Thanks in advance!
