Hello all, newbie here,

My wife bought this game last friday and we have been playing it all weekend long!! Love this game! But my question is how do you keep the health up of new babies? I have the research enviroment(2nd level),food research(2nd level),air thingie, 2 plants, heater, 2 tanks + selling tank. I cross breed the wasp goldbulb with the greenfin spotanus(magic fish) to get the crimson carp but the health bar is alway yellow and the fish dies when there about 16. I could never get them to grow to 20. Can someone tell me what I'm doing wrong or what I need to keep them healthy?
