I am new here, I have updated my profile so you should see all the info you need.
I have had fish before, well I have when I was younger and it was really my dads but I did a lot of helping.
Im now 27 married and my wife and I have just got a new fluval edge 46 litre tank.
My question is this, I have 2 x Dwarf gwarmis, 1 x red tail shark, 5 x neon tetras and 3 x male guppies.
My problem is 1 of my male guppies is forever at the top of the tank, he seems just to slowly move around waving his tail well more like loads of ripples. their are no obious signs of any damage to fins or gills, no marks, not breathing any differently to the others but he is there all the time. He may venture down to sleep (I have seen this once) and if another guppy goes towards him, well he tells them to go away, or he just glides beside them (but I am sure they are going to meet him just to rest and they are back down swimming happily).
He does eat, I use a mixture of frozen tables that have lots of treats as well as flakes, I like to mix it up for happy fish. If I tap the tank he shoots off but stays at the top and then moving slowly around again.
I dont have a test kit but I have had everything checked, more than once! I have had the tank for 1 month, I let it cycle, I add pure aquariam bacterial balls to keep the tank crystal clear, I so a 25% water change once a week with conditioner, very minimum nitrates, ph is perfect, Each fish were added seperaly, all 3 guppies 1 week later 2 x gwarmis, then the red tail, then the neons.
Any help or advice would be grand, I have read so much but nothing really comes close to what is happening.
in advance, Scuba Tom
