How many fish?
my Jewel 450 (450 litre) planted aquarium has settled down nicely.
Plants are doing well and params are;
Ammonia 0ppm, Nitrite 0ppm, Nitrate 5-10ppm, Co2 3 bubbles per second (although I doubt saturation reaches much above zero as gauge only starts to come off the blue, into bluey-green). I do 40% water change once a month. I would say 50% of the aquarium is taken up by vigourously growing plants. Inbuilt Jewel Filter. Overnight aeration to purge any Co2 and keep O2 levels high.
So far I have the following fish in my aquarium;
4 x Large Clowns. 4 x Chain loaches. 2 x Pakistani Loaches. 1 x unknown loach. 10 Pristilla tetras. 4 x Ancistrous. 5 x Mollies. 6 x Dwarf Neon Rainbows. 6 x Celebes Rainbows. 5 x Rummy Noses. 2 x Large Flying Foxes. 1 x Large Red Tail Shark. 4 x Threadfins.
I was wondering how many more fish could I safely add to the tank. I would like to add 2 more threadfins. 1 whiptail cat. 2 Corys. 4 Denisoni Barbs. 10 x Cardinals or Neons.
My current occupants are all in good health and most are brightly coloured, minimal respiration and some in breeding condition i.e the Threadfins and Pristillas.
