http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=25-gallon-tank#1 I have a 25 gallon tank with three goldfish, 3 red wag platies, 4 zebra danios, 3 ghost shrimp and a cory. Since I am new to the hobby give me advice. I found out that the goldfish should go, is this correct? beasty72 2008-07-02 http://forum.aqua-fish.net/?topic=25-gallon-tank#2 Exactly. Goldfish will grow and will need more space. And buy more Cories, they should be kept in groups of 4 at least. I keep 10+ Panda Cories together. jan 2008-07-02 http://forum.aqua-fish.net/?topic=25-gallon-tank#3 remove the goldfish as they do grow bigger than keepers realise, they will take up the tank space and they produce a lot of waste which will foul your water. I too keep a shoal of panda cories ( 8 of them) ,they need mates with 5them to keep them happy. mickey 2008-07-02
