Megaquarium – Hybrid List and Some Tips to Get Them Quickly

During the Freshwater Frenzy campaign, some objectives or trades will require you get hybrids. Beside this, taks with hybrids can also reward you with a big prestige boost. Here is a guide listing all the hibrids from the vanilla game, and giving you some help to get them.

How ro Get Hybrids Easy and Fast

Intoduction to Hybrids

A lot of species from the DLC can breed, but only three can give you hybrids: Guppy, Amazonian angelfish and Discus. On their requirement page, this is represented by a DNA icon.

Hovering this icon with your mouse and the game will show you two infos:

  • Breed two fish with the same color gives you the possibility to get a color mutation.
  • Breed two fish with different colors and you may get a pattern mutation, but also bigger probability to get a color mutation.

I didn’t dig into games files, but only bred hybrids during several hours. All the infos I give you come from my experience.

For now you may wonder “is there a mendelian genetic system, with genealogic trees ?” and I will answer you: I don’t know. And honestly, you don’t really need to know to successfully get all hybrids.

Same with mutations rates, I don’t have exact numbers but don’t worry this is not a ultra low rate. You can expect mutations at almost every breeding event if the parents have different color and pattern.

Now i’ll give you the list of hybrids per species, with screenshots to show them, and some tips to make it easier to hybridise them.

Guppy

The Guppy is the first hybridisable fish you unlock, and like in real life, it breeds really, really fast!

Colors

We have 7 possible colors variations:

  • Regular (brown, the one you can purchase).
  • Emerald (green).
  • Scarlet (red).
  • Aqua (light blue).
  • Fuchsia (pink).
  • Lilac (dark purple).
  • Saphhire (dark blue).

Patterns

We have 4 possible patterns variations:

  • No pattern (the one you can purchase).
  • Cobra (black stripes on the caudal fin).
  • Inked (large black spots on the body and the caudal fin).
  • Leopard (black spots on the caudal fin).

All colors can exist in all patterns, so we have a total of 28 differents guppies!

Scarlet and Sapphire

Fuchsia and Aqua

Emerald and Lilac

Regular-colored Guppies with a pattern get their own color: Cobra is Black and brown, Inked is orange and leopard is black and yellow!

Get all hybrids Guppies

As they will reproduce fast, the best way is to first randomly breed them.

First, build a tank big enough to house several guppies, and fulfill all their needs to get them breeding.

When you get your first fry, put them in another tank without adult fish, correct heating and high water quality. This will maximise survival rate, more guppies will grow into adult and that means more potential mutations. don’t forget floating plants and food, fry need to eat !

When they grow into adults, take a look ! first you will get only color mutation, I only get Emerald and Scarlet guppies by breeding regular ones. Take all mutants and put them in the first tank, you can also sell some regular guppies.

Now, you can continue this process trough several generations, with differents colors you will get patterns soon, and more colors, patterns etc…

After some time, sort your fish by color (using multiple tanks) and find out what you still don’t have, and work with pairs.

For example, you miss only Cobra Sapphire and Leopard Lilac?

Build two small tanks, Put one no-pattern Sapphire and one regular Cobra in one tank, same with one no-pattern Lilac and one regular leopard in the other!

Theory

I’ve noticed something, it may be wrong, this is only suppositions from what I observed!

It looks like there are 4 color categories (“generations”):

  1. Is regular guppy.
  2. Are Emerald and Scarlet.
  3. Are Aqua and Fuchsia.
  4. Are Sapphire and Lilac.

I noticed that I only got Emerlad and Scarlet when breeding regular guppies, and never got Sapphire or Lilac before Aqua and Fuchsia.

So we have three possibilities: I was unlucky two times with Sapphire and Lilac (campaign 3 and sandbox), or colors don’t have the same mutation rate, or you need to breed some colors first to get some others colors.

As nothing this is only a theory, don’t take it too seriously. But I’m interested if you want to share your experience about it !

Amazonian Angelfish

This one is a little different because we don’t have a mix with colors and patterns, mutations result only in differents skins !

Skins

We have 6 possible skins:

  • Regular (with some dark stripes, the one you can purchase).
  • Blushing (white with red cheeks).
  • Marble (with a lot of dark stripes).
  • Golden (entirely gold).
  • Koï (white with a big red spot on the head and some littles black spots).
  • Black lace (entirely black).

Regular

Blushing

Marble

Golden

Koï

Black lace

Get all hybrids Angelfish

You will need a tank where breeding needs are fulfilled for your fish. Put some Angelfish in, but not too much, they are territorial! They beed moderatly fast, and you can accelerate the process by adding more verticals surfaces in the tank.

  • When you get spawn, put them in another tank without adult fish and high water quality, to maximize the survival rate. Spawn will hatch and become fry. Don’t forget the verticals surfaces and food they need!
  • Once they grow, select all the new skins you get abd breed them in the first tank. Try to breed fish with differents skins!
  • Don’t hesitate to get rid of regular ones or build a new tank, otherwise the territorial trait will bother you You can even build multiple tanks to easily pair up fish with skins you want to cross.
  • Keep also in mind that after breeding, they have a cooldown of a few day before they can breed again.

Theory

I have the same “generations” theory I had with guppies:

  • Gen1 = regular.
  • Gen2 = Blushing and Marble.
  • Gen3 = Golden.
  • Gen4 = Koï and Black lace.

It’s because I only get regular, Blushing and Marble when breeding regular ones.
I don’t remember how I got Golden, but it was never with two regular parents.
I never got Koï and Black lace before getting Golden.

Of course those are only theory, I was maybe just unlucky or Koï and Black lace are just rarer ! If you wnt to share your experience about it, I’ll be happy to read you!

Discus

This one is the hardest fish of the three to hybridize, because it is capricious. But first, take a look at all hybrids you can get with it.

Colors

We have 3 possible colors variations:

  • Regular (pink, the one you can purchase).
  • Blue.
  • Yellow.

Patterns

We have 4 possible patterns variations:

  • No pattern (the one you can purchase).
  • Spotted (paler body color and deeper colored spots).
  • Striped (even verticals black stripes).
  • Heckel (vertical black stripes, some of them are thicker).

All colors can exist in all patterns, so we have a total of 12 differents Discus!

Regular

Get all hybrids Discus

As you can see, we don’t have that much hybrids compared to guppies. But it will take a longer time to get time all, because Discus are way harder to breed.

The pair need to be alone to breed, so you have to build several tanks (I had 10 couples so 10 tanks). Tanks have to be big enough because Discus is a territorial fish.

Be careful, if you have a lot of discus, you need staff members with very high feeding level becaus they are hard to feed and even require supplement.

Fulfill all fish needs (floating plants and verticals surfaces) and wait after them to breed, this is longer than other fish.

When you get spaw, don’t put them in another tank and keep the parents, because fry need to be fed by at least one of its parents ! (they also need to be fed by your staff).

After you took all the precautions mentionned above, you just need to wait until fry grow into Discus. Sadly, their natural survival rate is quite low, so put a lot of filters to get at least 105% water quality ! even with this water quality I lost a few fry (it’s rare but can happened).

So you will also need High level staff in fixing if you have a lot of discus tanks (using pumps will help you to not dispatch your filters everywhere).

Keep in mind that after their fry grow into adults, parents need to wait several days to be able to breed again.

Your first goal is to get blue and yellow Discus (you can get both from two regular parents), then you will have to cross different colors to get new patterns (you can get all of them no matter the parent’s colors, they only need to be different).

And when you get patterns, cross discus with different colors and patterns to maximize your odds of getting all of them!

The real difficulty is not about finding new colors and patterns, this isn’t that rare. The real difficulty is that Discus breeding is slow and require a lot of attention and patience.
