i have just found one of my lyretail guppies dead! the cherry barbs have been hassling him for a few days now, and they appear to have eaten most of his tail. i have two other lyretail guppies, one normal and one endlers variety, who i have had to isolate in my breeding trap until i can buy another tank tomorrow. it comes with a filter, but i cant work out the water volume so i can buy the right heater for it. i dont think there was anything actually wrong with the guppy, he was swimming happily yesterday, and hadnt gone a darker colour, he was almost luminous blue when i turned the lights off last night. am hoping the remaining two will be ok in the breeding trap overnight, i have taken the fry trap bit out for now. any advice would be welcome please. oh, and the tank i am buying tommorow is 22.5cm high, 24.5cm wide and 20cm deep, i need to know the volume in uk litres. i know its small, but they are only small fish, i will probably get a couple more to go in there so the two are not lonely, will probably have 5 guppies total, all male.
