All the fish seem happy enough,except the silver shark I lost today,but it too looked thin and I have only had them in the tank 4 days.
I think the dwarf and that shark may have come in with something or just stressed or something along those lines because the other fish came in from the same shop on the same day and they are fine.(dwarfs first then sharks 2 weeks later).
The lfs today said my tank was to clean was my problem,doing a small water change 10-15 % weekly,they reccomended 30% monthly???
Can't find peat,without fertilizer, in my area,tried ebay no good either,not in the lfs.
May just leave the pH as is.Don't really want to do chemicals, but the shops use them as the water supply is the same at my house as the shops. Can't do to much damage if I decide to go that way can it?
