The main differentiating factor is the black botch that’s located right beneath the dorsal fins. In males, this spot has a stark black color. In females, it has hints of iridescent blue here and there.
Yes, oscar fish sleep. They retire to their favorite corners at the bottom of the fish tank and call it a night. Like us, they have sleep cycles. And their body also produces hormones that regulate their sleeping pattern and calibrate their internal clocks.
When freshly laid, oscar fish eggs are white in color. They are slightly bigger than a salt flake – about a millimeter in diameter. But the following day or so, they start to look like a mini chocolate ball. Since the matriarch lays hundreds of eggs, it looks like someone just scattered some salt on the rock.
No, you cannot keep oscars with African cichlids. For starters, they come from two different corners of the world and need entirely different water parameters. Second, both oscars and African cichlids are aggressive fish. At least one party will be relentlessly bullied, which can lead to grave injuries and even death.
No, you cannot keep oscars with goldfish. I could bombard you with all the reasons they shouldn’t be housed together. But for starters, oscars will eat your goldfish 9 out of 10 times.
Yes, oscars have teeth. In fact, they have 2 sets of teeth – one in their jaws and another in their throat. The teeth in the jaws are small and used primarily for grasping. Whereas the pharyngeal teeth in the throat are used to manipulate and process the prey.
No, oscars cannot live in cold water. They are tropical fish from the Amazonian river basin where the water’s warmer. Therefore, oscars are not accustomed to cold water. If exposed, their bodies will react negatively quickly, and it can even prove fatal.
Oscars are semi-aggressive fish. However, in the wrong environment, they can be really mean. They’re especially hostile towards smaller fish whom they view as a potential meal. But when kept with similarly-sized fish that can hold their own, an oscar’s anger can be managed.
At first sight, male and female convicts look pretty identical. But there are slight differences. For example, males are normally a bit bigger than their female counterparts. They also have longer and pointier fins. However, the biggest giveaway is the orange tint in the female’s abdominal region.
African cichlids can live for anywhere between 6-10 years. In captivity, factors like their environment, diet, and exercise play a pivotal role in determining how long they will live.
Most oscar fish live for around 8-12 years on average. However, when given the right diet and care, they can easily live for about 15 years. The oldest known oscar fish reportedly made it to its 21st birthday!
Salvini cichlids were first described in 1862. They are ubiquitous across Central America, along the Atlantic slope from southern Mexico to Honduras, Guatemala, and Belize.
No, in most cases, cichlids cannot be kept in the same tank as tetras. Tetras are small fish, and the thing with cichlids is that they’ll try to devour anything they can fit into their mouth. Cichlids and tetras also require somewhat different water parameters to thrive. So, it’s a no-no.
Depending on the species, jewel cichlids can grow anywhere from 2.5-10.5 inches (6.5-26.5 cms) long. The maximum potential size in the aquarium is a lot smaller than in the wild.
No, cichlids and goldfish cannot live together for several reasons. First, cichlids are tropical fish that thrive in 76°F – 82° (24-28°) temperature range, whereas goldfish are coldwater species that need water to be around 68° to 74° F (20-23°).
