  • The game offers three different game modes, the action mode, relax mode and the sandbox mode. The action mode is timed and you have to complete multiple goals to get on to the next level. The relax mode offers the same levels as the action mode, only without the pressure of time. In the sandbox mode you can create the aquarium of your dreams and even the aggressive species will be peaceful.
  • If you become unsure concerning any facts about the species you always have the possibility to look into the almanac in the beginning of each level, which offers all the information you need.
  • Every time you reach the expert goal unlocks an item that you can add to your aquarium in the sandbox mode.
  • You have the possibility to click and drag the fish in your aquarium wherever you want to.
  • Every fish has a bar for its happiness which directly affects the price for which you can sell the fish later. The maximum happiness a fish can reach is twenty and this means a double worth at the same time. 
  • Be aware of the fact that cheaper fish generally sell quicker than the more expensive ones. If you’ve only to fulfill the money goal in the end and not much time is left it is more advisable to raise a larger amount of cheaper fish than only a few expensive fish because this step can decide whether you finish the level in expert time or not.
  • If you buy two betta eggs you will always get one male and one female betta. If one of your goals is to sell eight or more bettas and you have two "sale tanks" it is helpful to put two betta eggs in each tank at a time. In this way you can raise four bettas synchronous without the danger of two male ones attacking each other. However you have to be careful not to put other fish, which they tend to attack, in those tanks then.
  • If your goals include both plants and filter purchases begin with the plants because they help you to increase the profit by each sold fish. If you have one sale- and one breeding-tank it is also important to put plants which increase happiness in the sale-tank at first, because you cannot sell fish out of the breeding tank, that means happy fish are only helpful in the sale-tank.
  • Only buy helper fish like the ancistrus or the plecostomus if it is one of your goals. If not they only waste worthwhile space in your tanks and on top of that they are a very expensive purchase.
  • You should only purchase filters or plants which reduce dirtiness if this is part of your main goals, because either of them are rather expensive and do not help you to increase the revenue. Since the changing of the water does not cost anything you can save your money for more important things. 
  • The green algae that appears consistently in your tanks can be removed with the blue sponge. As long as you do not clean your tanks from algae you cannot click things which are behind it.
  • You do not have to wait with selling you fish until they are adults. Under the market tab you can always check the current worth of each species in your tank. To know that can be very helpful in two situations: (1) If your only goal left is to sell for example six Rasboras purchase six eggs and list them immediately after they have hatched out. (2) If the only goal left is the money goal and you need another 150 $ it is possible that you can earn this amount of money when your fish are just in the teen stadium. Again you can list them all immediately by clicking on the little $-symbol beside the species under the market tab. In both of these situations it is more probable to reach your goals in expert time if you sell your fish before they are adults. 
  • If you have a breeding tank it is hard to keep of the gender of the fish. However there are two different ways to avoid getting confused and thereby losing worthwhile time. Firstly you can always transfer the fry directly after they hatched because it is easy to distinguish fry from adult fish. Secondly, if you have a lot of adult fish in the breeding tank for whatever reason (for example you had to keep oscar fry in the breeding tank because you raised tetras in the sale-tank at the same time) there is also a helpful tactic to ensure that one male and one female fish will stay in the breeding tank – just click the breeding button and transfer all the remaining fish to the other tank who are not involved in the breeding process.
  • You are not able to sell sick fish. If a fish gets sick though he is already listed for sale it wont be sold nonetheless before it is cured again.
  • Some fish look very similar, especially the loaches and the tiger barbs. Be sure not to confound them if the sale of one of those species belongs to your main goals.
  • Be aware of the fact that algae diminishes the worth of your fish, so be sure to clean the tanks before you list fish for sale.
  • In the later levels of the game you will have to take care of two tanks at the same time. You can switch between them by clicking on the tab on the right side of the market tab. This tab will also inform you about the state of the other tab, that means there will be flashing messages if the fish are either sick, hungry or if the water gets dirty.
  • If one of your goals contains the breeding of a species that tends to attack or eat its own fry be absolutely sure to feed the adults regularly, always before the bubble which tells you that they are hungry appears.
  • Purchase plants which increase happiness as soon as possible but be aware of the facts that each tank only has space for three up to five plants and that the happiness of a fish cant exceed the number of twenty, which means that for example three melon swords are of no use.


  • The different species differ in their size, what they eat, the price of their eggs and their worth when sold as adult fish and how they get along with other species and their own fry. These are the different species ordered by their appearance in the game:

  • There are a lot of plants you can purchase for every tank and each plant either increases the happiness of your fish or decreases the dirtiness rate of the water. Plants also need different lightning in your tank, some plants work with the standard light which is in your tank from the beginning on, more effective plants can be added to the tank not before you have upgraded the lightning to 30 W or 50 W.
  • Reineckii: Light (standard); effect (Happiness +1)
  • Java Fern: Light (standard); effect (Happiness +2)
  • Anubias: Light (standard); effect (Happiness +3)
  • Java Moss: Light (standard); effect (Dirtiness -10%)
  • Pennywort: Light (30 W); effect (Happiness +4)
  • Willow Leaf: Light (30 W); effect (Dirtiness -20%)
  • Ruffled: Light (30 W); effect (Happiness +5)
  • Water Sprite: Light (30 W); effect (Dirtiness -30%)
  • Repens: Light (50 W); effect (Happiness +6, introduces parasites)
  • Aromatica: Light (50 W); effect (Happiness +7, increases the probability of parasites by 5%)
  • Melon Sword: Light (50 W); effect (Happiness +8, increases the probability of parasites by 8%)
  • Wisteria: Light (50 W); effect (Dirtiness -50%, increases the probability of parasites by 10%)


  • There are three different kinds of medicine. Fortunately you can quickly recognize when a fish gets sick by a bubble beside it. Inside the bubble you will see which medicine this fish needs at that moment, his can be either antibiotics, methylene blue or dimilin. Admittedly medicine is more expensive than food but it is still rather cheap so you do not have to worry, you will always have enough money to provide medicine if it is needed. However you should react quickly if one or more fish get sick because their health bar will run down then and sooner or later they will die.


  • You can upgrade the filter in each of your tanks three times. The undergravel filter will reduce the dirtiness by 25 %, the bio wheel filter by 50 % and the canister filter by 75 %.
