I've got a 180l tank and am thinking of getting a couple of 3 spot Gourami's. Any advice before i take the plunge
?
I currently have
2 x Ancistrus
7 x Blue king tetra
6 x Cheery barbs
I am looking at adding 2 Gourami's, a Chocolate Zebra Plec and a shoal of about 12 Cardinal Tetra but I'm flexable on this as don't want to go overboard(my lfs say thats ok however I realise they will tell me anything to make a sale).
I'm upping the filtration in the tank to about 1300lph and not going to put anything in until I have done this.
Any advice,ideas or comments?
