My tank is 3ft long 1ft wide and 1.2ft tall. My tank has a Fluval 2 plus filter and is heated by an Elite heater(Sorry dont know the model name).
Before you buy any fish i would recomend that you research what the fish need or you will find out the hard way like i did and loose fish.
In my fish tank i have currently got three bala sharks, two red eye tetras, two bristlenose plecos one male and a female. I also have a large angelfish that is about 7 inches tall.
At the moment i only have one plant and i dont have a clue as to what it is.
When you see signs of stress in your fish, you can then take steps to identify the source of that stress and then to resolve it before it becomes a major issue.
If you're looking for a unique way to stock your new tank, give freshwater shrimp a try.
If your fish is suffering, you may want to consider euthanasia as an option to humanely end his pain.
