I decided to post another thread because I really can't do much with my aquarium until I have an answer to this...
I'm setting up a 10 gallon aquarium (I have a 5 gallon currently) and Ive planned all the steps out up to the point of introducing the first fish. I need to know what species can withstand cycling.
The tank will be very heavily planted and I'm putting the filter from my current tank into it to help get the cycle established.
The fish I already have, which will be moved to the new tank once it's mature, are an angelfish and a gold gourami. I'm planning on getting some tetras, a pair of rams, a bristlenose catfish, and maybe a red-tailed shark but obviously none of these fish are suitable for cycling.
two ideas have come to mind but I'm not sure if they'd work:
cycling with water snails (which is how I cycled my current tank)
or golden barbs. I have a golden barb which is currently living in an outdoor pond and on deaths door :( hes very sick but previously has always been incredibly hardy, able to withstand almost any conditions. would a shoal of golden barbs, perhaps introduced gradually, be good for cycling a tank?
i really need an answer to this, i can't get on with planning my tank without knowing :)
