they might be bottom feeders
bottom feeders are fish that feed on or near the bottom of the tank, and may also eat off of plants. some examples would be loaches, catfish, plecos.
if u have a fish net gently swirl it around near the bottom of the tank. if he doesn't run away.he might be dead or sick. if there r other fish inthe tank with him moov him to another place even a bowl of water.
That refers to where the fish eat; near the surface or towards the bottom of the tank.
It is not a bad thing that all of your other fish aren't on the top of the tank. It is possiable that all your other fish just like being near the bottom. For some fish it gives them a more secure feeling being near the gravel at the bottom. If your fish look unhealthy and you think there is a problem you need to ask a different question describing the symptoms.
Tropical fish stay at the bottom corner of the tank because they are either cramped up, if the tank is small or the fish species is just like that
This may mean 3 things: # It may be tired, # It may be sick or injured, # Or it could be near the end of its life.
they just settle at the bottom of fish tank
Maybe the bottom of the tank is cleaner? You should go to a place that sells fish and ask them. Good luck:)
Because there is more oxygen at the bottom of the tank. Not for our type of lungs but theirs
coz the fish needs light on a big tank
maybe its dead although usually they float. depends what colour it is.
I suggest that you learn more about your fish in your aquarium. One of your fish might be a bottom sucker which means that they eat all of the dirt on the side or bottom of your tank. If one of your fish are bottom suckers, that's probably the reason why your aquarium is clean. If none of your fish are bottom suckers, than somebody must be secretly cleaning your tank for you.
Betta fish forage for food at the bottom of there tank if there hungry and if there is food in there because they eat non stop.
That fish has ceased to exist. It is an ex-fish.
Fish eggs, fish sperm, mold.
You simply take any fish and drag it to the bottom of the tank and then drag it up (fastly) and it will go soaring!
They want feeding.
ummm your fish is dead....sorry.......
Could be anywhere.
