- Do not buy a fish from an aquarium where dead or dying
fish are. Chances are there are health issues already present
in these aquariums that have likely infected even the fish
that appear healthy.
- Before buying a fish be sure to inspect its physical condition
and avoid ones with any visible damage. Our beginner
tips page goes into more detail about this point.
- It is important not to add many fish to one aquarium at
the same time. They will almost certainly fall victim to new
tank syndrome. Adding that many fish can also disrupt
the balance of the aquarium.
- For the first few days after setting up an aquarium and
adding fish it is vital that you do not overfeed them. Overfeeding
your tropical fish causes the tank to become polluted during
this very unstable time. Overfeeding can also cause significant
growth of algae which can be damaging to the new fish.
