Is my aquarium overstocked?

My 3 feet aquarium is filled to 30 gallons and i have a cannister filter which does 380 litres / hour plus an internal filter which at first i added contained by to help cycle but now decided to hold on to it in there. there are 48 neon tetras, 4 clown loaches,8 other tetras which i dont know the type, and 9 guppies. The aquarium is 4 weeks ripened and it is heavily planted, so far the fish have been fine and the condition of the water close to ph nitrites, nitrates and ammonia seem to be fine and stable. Is it overstocked? if so poorly move some of them fish into my other aquarium.
Well not really if your dampen is fine. If your tank is overstocked your ammonia,nitrite and nitrate would be thru the roof. The thing you need to be most concerned beside is the clown loaches. They are gonna need a much bigger tank than that. Do you have them to control the snails ? After your snail problem is gone return them and bring some Cory Catfish instead and you should be fine. Don't let the guppy's breed either or you will have problems. Good Luck
Is that portrait really your 30 gallon tank? That tank look much bigger.

If it is really 30 gallon tank, after 4 clown will soon become too big for that tank and will need to be moved.

Simply monitor you ammonia and nitrates (and nitrites). A spike from normal is a biddable indication that your tank is normal. If you can maintain not anything ammonia level and less than 30ppm nitrate level, you should be fine.

There is really no rock-hard rule to determine if a tank is overstock except to determine your water parameters.
Yes, you're overstocked. But you also overfilter, have live plants, and are stocked with small non-aggressive fish so minus the clown loaches you should be OK. It purely probably wouldn't be a good idea to add anything else, you do want them to enjoy some room to move in there. :)
Just to grant you an idea of how overstocked your tank is, (no offense) The most neon tetras you're really supposed to keep contained by a tank that big is about 25. And that's when there adjectives be themselves with no other species. And are you sure that your tank is 30 gallon? It looks a touch bigger than that in the picture.
yes, that is very overstocked
i would just get hold of a bigger tank and put the clown fish in to it and keep the rest where on earth you have them
Answers:    You just gave a new connotation to overstocked. Seriously...

The clown loaches... First off, these guys grow to 12 inches. For a group of 4, youd need at least 150+ gallons. Then... The tetras... I can see someone undamagingly getting away with 20... Even 30 tetras in here... But 48 is just way too much. And the 8 other ones... And the guppies... Yeah. You need to move rather a bit. You could keep about 30 tetras in in that if you know what you are doing (which it kinda seems). But everything else will need to go somewhere else...

If its impermanent, youll be fine. The loaches do reach 12 inches, but they are very slow growing. Like a 2 year old loach would be lucky whether it was 6 inches.

You might be fine, but honestly, it just seems a bit much to me. Ive get a 29 gallon tank with 15 bloodfin tetras and 5 cory catfish in it, and I couldnt think anymore in there. I see you said heavily planted, that right there might amass you. If you arent new to this, you might be able to pull it rotten.

But I dont think it would be the ammonia and nitrates and stuff that would be the problem. Neons produce so little waste. 48 fish that school together... Its going to be crowded for them.
