Symptoms of a Fish Tank Problem | Aquarium Care


Some people who are not experienced don’t
really know what to look for, so certain symptoms that you want to look for to diagnose problems
or potential problems would be the following: you can look and see if the fish are eating
as they normally eat. If fish stop eating or a couple of fish don’t
eat, that may be a sign that something’s going on in the tank. Just like people, when we feel sick, we don’t
usually want to eat. If the fish are reluctant to eat, they’re
sitting in the corner, maybe they’ve got a little shimmy or the fins are clamped, those
are signs that something is brewing in the aquarium, and time is of the essence. If you see that something’s wrong, your fish
that are normally very responsive and right at the top of the tank to consume food are
now sitting at the bottom of the tank, something’s wrong. It could either be water chemistry, or maybe
you’ve introduced a parasite into the aquarium from adding new fish. Whatever it is, you want to jump on it soon
before it becomes a full scale problem. Look at the fish, see if they have any symptoms
on them, if there’s any body slime, if their eyes are a little bit cloudy, if they have
white spots, and then either research these symptoms online further to see what could
be wrong, as certain symptoms on the fish can be identified. White slime could be ammonia buildup, red
burns on the fish could also be ammonia buildup. White spots on the fish could be a parasite. Cloudy eyes could be an external trematode
burrowing into the eye. Nasty stuff, but these are the symptoms you
want to look for. You also always, anytime something seems out
of whack, test the water. Make sure your heater is functioning. Sometimes heaters stop working and you don’t
even realize it. Your thermometer broke months ago but the
heater has been working, and your water temperature is too cold. The only way to know this is by looking at
the fish and seeing that they’re not eating as much, so you do a full-scale test. Test the temperature, test the pH, test the
ammonia, test the nitrite. Make sure all your filters are plugged in
and they’re all working. Sometimes filters become clogged or they just
stop working mysteriously and they go unnoticed, and the tank has been running a couple of
days without a filter. The first thing you want to is look at the
fish and see how responsive they are. They are like the canaries in the coal mine. If the water gets a little cloudy, that could
be a symptom that the tank is getting a little out of whack. Maybe you haven’t done a water change in a
while. The filter is clogged, and now the bacteria,
which can no longer live in the filter because it doesn’t have the water flow it needs, it
is now growing in the water column, so the tank is getting a little bit murky. If you see a lot of waste settling on the
gravel bed, maybe your filter is clogged and the flow has slowed down to a point where
it’s not keeping the waste in suspension and now the waste is settling on the bottom. A large buildup of algae would also signify
that there are a lot of nutrients available that may have not been available months ago
when the tank was working properly. Again, look at the filtration. Maybe it’s slowed down, maybe it’s time to
clean it. Fish grow, and as they grow, they excrete
more waste and they need more food, so the rules that applied last year or six months
ago may not apply now. Your fish have doubled in size, and now the
tank may be overcrowded where it wasn’t overcrowded six months ago. All of these things should be things that
you’re looking at.

  1. I miss the old Howcast. It was way more interesting than this. I just miss how they would give tutorials not……. Information and facts. Blahh.

  2. I have white floating particles in my tank they are not on the fish or glass or air bubbles …wtf are they… can anyone help ?

  3. Some one tell me what type of fish breathe from air? I need to know about that because I don't want filter or air pump so I want to know what types of common fish can survive without air pump. I have 3 gallon tank but I don't want air pump!!

  4. My red fin molly seems to stay in the top corner of my new tank….just set it up and it is a 75 gallon tank. Plenty of friends and filter is new and the tank is clean….but this one red fin wants to stay at one of the top corners..???
