Hi, I'm fairly new to fishkeeping myself and have a 3 foot tank. I can tell you my experience but others may tell you otherwise, prob be best to go with them. All i can say is don't buy any fish without researching or asking a fishshop guy who actually knows something (there are a lot that don't). And don't impulse buy it's an easy way to overstock and kill fish which just ain't nice.
when i started i got Guppies for the cycle (maybe shoulda fishless cycled but they're all fine, didn't lose one)
I then started to add fish and get babies from the guppies (they're like rabbits and will stock your tank fast)
Personally i like tetra as they are so calm and rummies in particular scholl well and move around plenty to provide a little movement in the tank to between 5 and 10 is recommended, no less or they get unhappy
you will then want to get some bigger fish i imagine so i would recommend dwarf gourami's but beware that they are easy to lose and preffer a mature tank and hiding places. I just lost one of mine and i fear for the other
An almost definate for any tank i feel is a red finned shark. They're great darting around being inquisitive about everything including other fish following and chasing them but never violently.
Angels are lovely but i recommend smaller ones as angels can be pretty terratorial when larger and can become agressive on occasion. My two do whenever new fish are introduced but a bit of time in an isolation tank sorts them out.
You may be tempted to get barbs as i was. but don't if you have any longfinned fish cos they nip and chase other fish (my brothers didn't when he got them but now that they're old he introduced an angel and they terrorised the little thing untill it got together with the other 2 larger angels). Also not good for breeders of other cos they eat all the babies like the angels will.
Probably the most expensive fish i have is my plec (Glitter Plec) at £25 but he's lovely and with serve to clean my tank. also a must have
I also have khullie loaches which are also really cool slithering around the tank. They also need hiding spots and can be less hardy then other fish due to the lack of scales (they will die in salt btw)
I always feel that a crustacean or a frog help to even out a tank.
My brother opted for a crab but as cool as he is (and he is really cool) he will try to eat everyfish you have unsuccessfully at current, as well as rip up your plants and try to escape. (he will also scare the hell out of you when he sheds his skin leaving a replica of himself making you think that he is dead when he's behind the rock sniggering away at you
I opted for a shrimp (attya gabbonese). 2 actually and they don't rip up the plant but they also don't like coming out, seeing them is a rarity if you provide hiding spots (don't give them a lack of spots just so you can see them, It's not fair play and it's not good for them. The ones i have are filter feeders sticking out sieves in the water and harvesting bits in the water. Not killing the kish.
Last but not least, my favourite(est) fishies and my newest are my 2 German Blue Rams

i love the colours, they love to chill with my guppies and are not badtempered at all so far, (apparently they can be when breeding). Only thing is, my angels took offense to their prescence at first but have warmed up to them now.
My shark also chases them purely because they start to run so he thinks they're scared and can chase them, if they stayed still he wouldn't care, oh well
PS: i find that site very handy as well as the graph that it has
