Fish trying to kill each other HELP!!!?

Question

Do electric blues and rainbow sharks usually mix? Just one of each in a 3 ft tank?

Answer 1

Africans need alot of room and a lot of tank scaping to be comfortable. Rainbow sharks will not do well with them because they are not as aggressive as the africans. When you say you have a 3ft tank how many gallons does it hold - because that is what is important to know. Remember one inch of fish (not including fins) per gallon of water. Sharks are typically nocturnial and require lots of places to hide. Africans like to hide as well put when you have a community of africans they do much better as a group and you never know they may spawn for you which is great to watch.

Answer 2

African and South American cichlids have at least a few different requirements.
One is that as long as the water is well circulated and aerated, Africans can almost be crowded into a tank. They need plenty of caves/hiding places, like at least one per fish. The reason it's best to crowd them is because with just 3 or 4 fish, the one at the bottom of the pecking order will likely get killed, till only one is left. With a seemingly crowded tank, no one fish gets picked on too much.
Sharks are not a good fish to keep with Africans, nor are most non-African fish.

Answer 3

hi
you didn't say how big your aquarium is or what kind of fish you have. It could be due to overcrowding. 10 goldfish in a 10 gallon would be overcrowding, but 10 tetras in a 55 gallon wouldn't be. Even if they aren't overcrowded, introducing 10 fish into a non-cycled tank can have disastrous results.

Crash-course in fish care:

Usually pet fish die for one of two reasons; too little oxygen or too high ammonia concentration. Fish wastes consist mainly of ammonia. High ammonia concentration affects the rate at which they can absorb oxygen through their gills.

When deciding how many fish you want, you need to take into account their fully grown adult size, which varies depending on the variety. The rule of thumb is about 4 litres of water per 3cm (length) of fish. (oor one gallon per inch of fish) Talk to anyone at a real pet store (not Walmart or department stores that happen to sell fish) about fully grown sizes of fish.

It is important to do weekly 25% water changes to refresh oxygen levels and bring down ammonia levels. Never wash fish equipment with soap. You shouldn't need to rinse gravel or any decorations but once a year (rotate what you do rinse). Every surface under the water is a place where beneficial bacteria can colonize. These beneficial bacteria convert ammonia wastes into something less harmful for the fish. When there is a sufficient amount of bacteria to keep ammonia levels down, this is called cycled. It can take up to two months for a tank to become cycled.

If you have algal growth, you can scrub with an algae brush or sponge. If you have a heated, tropical aquarium, you may get some variety of algae eater that gets along with your fish variety (again, ask the sellers of the fish).

If you have a large aquarium (5+ gallons) you should consider filtration such as a bubbler type for under 10 gallons, or a hanging filter for larger tanks.


good luck

Answer 4

no they don't
you're mixing cichlids with sharks, which is never a good combination

and a 3 ft tank, is really small as well




Hope that helps
Good luck

Edit*
You can't apply the 1 inch of fish per gallon on cichlids
if you could, you wouldn't need at least a 75 gallon tank for 1 oscar, which get's to be about 16 inches right?

Answer 5

These type of fishes don't usually mix.You should put them in separate tanks to stop all the fighting.

Answer 6

some animals are just territorial,maybe you should seperate them...

Answer 7

anytime you buy a fish, ask the petstore etc if fish can mix together. they will always know :)
