How do you keep fish from dying in a fish tank?

Answer 1

When starting a new aquarium sometimes it is best that before you put any fish in it that you let it cycle (let the filter and other equipment run) for about a week or two. This helps the good bacteria needed for fish survival to build up so that when your fish is added it doesn't struggle with building it up himself.

The problem that we have ATM is that all our fish seem to be dying with no sinlg eclear indicator. Firstly, we have a 250 litre tank with 1 upside down catfish, 1 Indian algae eater, 3 white clouds, 9 red cherry barbs, 5 green tiger barbs, 2 rainbow sharks and 3 clowl loachs (plus a khali loach but u never see him) .. within the past week, our fish have jsut been getting knowcked off one at a time. There was a juvinile red Oscar (beautiful colour) that died, then 2 of the adult tiger babs, then a rainbow shark and now the upside down catfish and other rainbow shark are showing simlilar symptoms.

Symptoms include;

Very eratic swimming, often nose divingn into the groand.

the Barbs swam near the surfae which was very unusual

dorsal fins were split

often a los of color

often seen doing corkscrews and swiming in a spiral direction. (regardless of species)

I have taken the water samples to the pet store and they have told me that the water is perfect, just finished its cycle and isbalanced in amonia, nitrate and pH.

The tank is large so cannot be overstocked

Please help if this seems at all familiar to you or if you could help me out!!!!

Thanks!

You research proper fish care! And it will depend on the species of fish also. Basically it's your job as a fishkeeper to keep the water quality healthy, this will be achieved by making sure your tank completes the nitrogen cycle before hand, it must be filtered (unless you're going for a Walstad/El Natural set up, which is pretty technical also) and it must meet the requirements of the fish species you are keeping. An overstocked tank is going to end in failure, an unfiltered ill-maintained tank will also fail.

Basically to keep fish happy and healthy in an aquarium it's down to you to do as much research and possible! You can never stop learning in this hobby. NO ONE knows everything!
