fish have a 2 second brain span, i dont think they could learn that unless it was a big space between them not like a hamster tunnel size

that has been disproved u know :D

Remember just because someone does something, doesn't mean it should be done. If I was you I'd go with a 10-20g nano to start with. That way (if your a fish person like me) you will have more choices of what you could do available to you.

You're thinking of the common belief of "goldfish have a 2 second memory". I don't know if this is true or not. My experience with goldfish leads me to believe that it's BS. They are capable of exhibiting conditioned responses. ie. Swimming to the surface for food when you approach the tank.

Intelligence in fish varies between species and even between individuals in a particular species.

i'll be getting a pico or maybe even a nano because it will teach me the ropes before i set up my 60g sitting in the garage.

Kind of like people LMAO! lol
yeah i thought of that after lol about that whole brain span thing

well i know thats not true because i have a pleco that goes into the same hole every time i turn the lights on in my room :) any suggestions on what i should do?

If you're going to set up a 60 reasonably soon anyway I would just forget about the nano/pico entirely. A 60 will be a lot more forgiving in terms of stability than a nano/pico so you'll end up saving money and frustration in the long run. Just go with the 60 and start slowly (imagine its a pico/nano if it helps). The problem with really small tanks is if anything goes wrong, it goes really, really wrong and you lose most of your livestock. In a larger volume tank that rarely happens because there's enough water to buffer the effects of whatever potential mistakes you'll make.

would i be able to have a fish only tank then add live rock then add corals after a period of a few years?

If you're talking about in your 60 then yes. In a nano, pretty much no. Live rock acts like a filter and hosts a ton of beneficial bacteria/etc. used to break down waste products expelled from the fish. So you'd end up having to filter/skim or somehow otherwise regulate and purify the water in your nano w/o any sort of liverock. It would end up costing you a lot of money upfront to do that, especially considering you say you'd eventually want liverock anyway.

I'm not sure if you're considering this based on your estimated costs, but I will tell you outright that nanos are not cheap. Since you seem pretty undecided on what you want, I would sit down and make a list and say I would like this, this and this in 2-3 years and then compare that to the price figure you have in mind and see where you stand.

Also I wanted to add that if you really have a 60 gal and presumably the stand/some misc. equipment to go with it, it's definitely a no brainer to go that route regardless of what you do. If you get a tank set up, every reefer will tell you that you're always, always, always going to want more room.
