ok, i will hold my hands up... since i got the tank i haven't tested my water once. I know this is really bad and i WILL buy a testing kit but at present i don't know my PH.
I am aware that it will take a couple of years for everything to grow to adult size, by that time i hope to have a much bigger tank (50-60 gallons)
I want something that can brighten the tank up, something interesting to watch and colourful. I have googled this non-stop and just keep finding contradictory answers.
I ideally would like another schooling fish, maybe 6 again? If I could, i would have got some neon tetras but i know this is out of the question. I also like the rainbow betta but know that the barbs would destroy its tail fin
Thanks for your reply! :D
edit: Sorry, i forgot to reply about the filter! I used AqAdvisor
to calculate my stock. It says that the u2 isn't efficient enough :(
