Hi friends!
Thanks for all the feedback, once again you've been a great help
Waterdrop, I managed to get a beautiful 28 gallon tank for Fluffy for a really great price; I think the fish are much happier with the extra space.
Jazzzz, I couldn't do otherwise. I grew up in a family with lots of pets, ranging from cats and dogs to rabbits and a pigeon (fully domesticated, would fly up on my shoulder while I was playing the guitar!) I think that above all, it is respect for our fellow "planet Earth" inhabitants - especially those in captivity - to take the best care of them. As for my studies, I just finished my PhD in Computing and I'm awaiting my viva - patiently!
Silverrabbit, you're totally right about Fluffy's state of health. He's lost his previous vivacity and is now mostly staying at the top of the tank (but still swims near me when I send him kisses from the top of the tank; somehow he recognises the sound and seems to enjoy it!) I'll go to the pet-shop today and get Melafix and an air stone, also ask for Susie to go back to the pet-shop tank and reflect on her behaviour!
There is a friend who has a big aquarium and could put her up; the problem is she lives in Stirling and I don't know how to carry Susie all the way there. I don't think she'll be ok in a bag for the 1-2 hour journey (depending on traffic). To be honest, I think I'd like Fluffy to stay by himself for a while and recover. I don't think I'll be rushing to get another fish in the tank.
I'll let you all know of the results when I come back from the pet shop. In the meantime, enjoy the sunny day - I hope at least that it's sunny where you are
