i have a 29 gallon and when the fish are full grown i will be overstocked by 12 inches
is there anything i can do besides get a new tank?
wat r some good ideas?
weekly water changes?
Perhaps it would be a good idea to return this thread to it's original purpose..... namely avirex's stocking issue.
Avierex, as you have already stated you will be overstocked by 12" (according to certain stocking 'guidelines') when all the fish are fully grown.
As you will no doubt be painfully aware the 1" per gallon rule of thumb is really only a guide and only applies to smaller fish.
Personally I think it is a very worthwhile guide for when starting out (but opinion is divided on that

)
But as mentioned earlier (by most people) this is NOT a hard and fast rule and it CAN be broken.
But breaking it can lead to problems if you are not careful in managing your tank, the fact that you have asked the question, shows that you care about the health of your fish.
If you are to avoid problems there are a few things you will need to do.
Things that will help keep any problems under control include ............
Adequate filtration: I dont know what the flow rate of your filter is. Your tank is 29gal ..... what is the max tank size for your filter ?
If you are going to overstock, then you are better off over filtering to remove the extra bio load.
If increasing your filtration, you may need to deal with the ammount of current flowing around the tank .... some fish love a current (danios) some fish are not so keen (gourami's).
Regular water readings: If you are overstocking, you should keep a regular eye on your water quality (I'd do at lest weekly checks to start with).
Particularly your NH3(ammonia) & NO2(nitrIte), but also your PH and NO3 (nitrAte) would be a good idea.
I would consider this to be the most important step, as it will show you if you are having problems ans you can deal with them before your fish suffer
Regular water changes: Changing 10 or 20% per week will help control any buildup in the water, if you get any ammonia or nitrIte spikes when doing your water readings ..... do a partial change.
(the answer to pollution ... is dilution !)
One thing I would avoid is adding the range of chemicals available from most LFS's that promise to cure all your problems (they are usually expensive and not guaranteed to work), far better to cure the problem than mask it !
None of the fish you list in your sig are going to get too big or have an excessive impact on the amount of waste produced (thankfully no plecs!), so with regular maintenance you should be able to cope.
There are no doubt other things that you can do .... maybe somebody else can offer some advice !
