u have to have the right enviroment research to sustain a rare fish the rarer the fish
the higher the enviroment research has to be

They might have a diesese

if your not over feeding or stuff then the answer is...DRUM ROLE PLEASE!!!!DA DUM DA
DUM!!!!your tank dos'nt have any ordaments.YOUR FISH NEED TO LOOK AT SOMETHING YOU
KNOW!!!!

well try to see if they have disese and if they don't try researching fish enviorment
then then try to visit them more often or mabey their tank isn't clean........

you should try to buy the aeration system. it really works

You need to research the environment

put the aeration system in it keeps them alive

keep your fish fed trust me I did this and it worked on the same problem

u ee....****** coz u cant play the game

if i were u, i wud visit my fish more often, then, if i see their health steadily
declining, i bombard vitamins in their tanks, well that is, if u have plenty of money.
that's how i got all 7 magic fish breeds w/o buying the full version, just playing online.
hehehe. it is also a great use if u segragate the stable fish from unstable ones, and take
note of the game speed, too. set it to paused or slow if u have unstable breeds, but only
if ur not breeding. i don't know if the same parents (ex:greenfin spotanus + greenfin
spotanus) vs. different parents (ex:twin-fin spotanus + spined spotanus) can yield better
nd stabler breeds. hope i helped!

when you start a game buy the airation system and the heater system as soon as
posable.then if your fish start losing health and their fed meter is not full it is
probable a deases so throw it away instead of buying cures.also make sure your time is
right because if your time is on fast you have to cheak on your fish more often.

you might be over feeding them
make sure you dont over feed them
fish die if they are stuffed
trust me i lost all my fish this way and had no money left

dont overfeed them

the filter does work and the ornaments atract more people

feed them enough, check on them and air system + temp. regulator
