I've finished the game several times on both Windows and Pocket PC. The better strategy is to keep your fish alive longer so that they drop diamonds instead of coins.
I had Insaniquarium 2 when I was 12 (addicting as HECK) and I eventually had every "pet", so I had A. A pet that helped to makes more money, B. the punching-penguin pet that makes money come out of any fish, and C. an automatically money-collecting fish. It was epic. I also reset the clock like five times a day to keep the shop circulating; I ended up with an invisible color-shifting tye-dye mega-piranha. Suffice to say, if this came out on iPod (replete with DLC?), it would be pretty awesome. PopCap's ports are darn faithful, I must say, and Peggle is as addicting on the Touch as is is on the computer. -3D
Comic Aquarium Hi! Check out Comic Aquarium!! It's similar than Happy Aquarium or Insaniquarium but with it's own comic-style. Coming soon for iPad and iPhone (a bit later). http://www.youtube.com/watch?v=mxsoFU2Pvpw www.comicaquarium.com
Insaniquarium would be brilliant especially on the ipad another game i would love to see ported is Jet set radio
*digs up this old grave* Its called Fish Guardian in the app store for only 1 dollar. its a perfect clone.....unfortunatly also a bit illigal in m eyes. check the edits below. this is a game ive been waiting for a long time.... now the iphone is immortal both available in normal and HD version for ipad. ipad: http://itunes.apple.com/app/fish-guardian/id421125033?mt=8 iphone: http://itunes.apple.com/nl/app/fish-guardian/id423526338?mt=8 lite(iphone-sized): http://itunes.apple.com/nl/app/fish-guardian-lite/id424007096?mt=8 this game is EXREMELY addictive IMO so be warned EDIT: although i very much like this game, i recommend you to download this NOW before it disappears. it uses desame sounds and copies really everything. also for support their website says justrungame.com and does not work. a bit suspicious. Also by playing the game i can tell it has been made quickly, with not much effort put into it. the sound quality is also a bit crappy and main menu sprites are simple, do not animate, and the english is really bad. but, it is the real insaniquarium we have here! so download before it's gone! lite(iphone-sized): http://itunes.apple.com/nl/app/fish-guardian-lite/id424007096?mt=8
