I currently have 2 17L (4.5g) tanks on the go.
The first contains 1 Betta and 6 Pristella, it has been runing for roughly a month with the fish. When i purchased the tank the store owner said changing the water as little as possible would be best. The fish seem fine and I dont see any problems with the water quality.
My problem is this
I know the water will need changing Im not certain how often and how much as every where I go I get different advice and so far have decided not to tempt fate (my father attempts at fish keeping in the past often resulted with mass culls when changing water).
So how, how much and how often should i change the water in these tanks?
Should i leve the guys in there?
The second tank is being preped for shrimp or lobster anything special I should do to prepare this tank, the store owner said just to prepare the tank as I would for fish.
Thanks for any help, I just dont want to kill off the fish by leaving them in rancid water or shocking them when i change the water.
