Red face overstocked??

Hi I recently set up a new 125l (33 us gallon tank),
I cycled the tank for 4 weeks before adding any fish and added some prime to the water to get rid of chlorine.
i have 2 medium sized plants, a bridge ornament, a large half shell that doubles up as a cave and some driftwood.
i was wondering if i could get an opinion on wether my tank is overstocked.
I have:
1 blue dwarf Gourami
1 male betta
1 female betta
5 black skirt tetras
11 neons
2 rummy noses that shoal with the neons
1 small angelfish
a bala shark
2 pakistani loaches
1 penguin tetra
2 male and 4 female guppies
the only fish there that i know will get quite large is the bala shark and i plan on giving him to my best friend with a much larger tank when he gets to big!
all of my fish seem to be gettin along fine ( no ripped fins or injurys)
the reason i ask all of this is because my dad has his heart set on getting a small gold severum that can grow up in the tank as he has heard that they are the least agressive chichlids and that if they grow up with the tetras from a young age they wont see them as food?

Thanks for listening lol!

i assume you did the fishless cycle. if so, did it complete its cycle before you added fish or you assume that after 4 weeks its cycled. doesn't sound like your overstocked as long as its cycled. as far as the cichlid, research it to make sure the water parameters that you have with your current fish, if it will suffice the cichlid as well. i know most cichlids like the higher ph range.

First and formost, yes you are quite overstocked........Dont take it personally, but you need to rehome some of your fish........The male and female betta will each need there own tank.....Keeping these 2 fish in the same tank is asking for aggression problems......Only to breed them, should they be kept together and sometimes even then they will fight to the death.......
The angelfish will become an issue for you also as it gets larger, more than likely its gonna eat your tetras....
The bala shark is going to get alot larger than your tank can accomodate for him (Which you already stated), plus they like to be kept in small schools......
The gold severum will not do well with the other fish in question, yes they arent as aggressive as some cichlids, but they will also eat your tetras and guppies.......Just to clear one thing up for you, the water parameters for the severum are relatively close to what your other fish are in now......The statement about cichlids liking a higher Ph is for AFRICAN LAKE cichlids...(Malawi, Victoria, and Tang????ka)..........South American and Central American cichlids will do fine in a lower Ph

The only suggestion i can make is get a larger tank or rehome the for-mentioned fish..........

looks ok in the pic but it's a bit overstocked. Good that u will get the bala a new home. I'm not a fan of keeping a lone angel.
the yoyo loaches will also get quite big.
Adding a severum is an experiment you dont want to do, i think.

If it was my tank, i'd get a second tank and split up the tetras and guppies from the rest

Matilda & Philippe & Limu the Lab

47 gallon (180 litre) colisa tank
106 gallon (400 litre) Gourami tank
317 gallon (1200 litre) angelfish tank

your guppies will end up breeding like crayz since they are livebearers
tetras need to be kept in a school
like fishinpole said....the two bettas are not a good match together
you're going to need a bigger tank, even then some of the fish mentioned by fishinpole will still not be compatible

I agree with fishin pole and JohnnyD. The bettas need to be seperated.

The part about fish not seeing smaller fish as food if they grew up with them is mostly a myth. Sometimes it works that way, but usually the smaller fish eventually dissapear.

As the Angel grows it will likely eat any fish that will fit in its mouth. You might get lucky, but maybe not. Neons are part of wild Angels' diet. Keeping them together usually ends badly for the neons. But it will probably be a while before his mouth is big enough.

the orginal question was if the tank was overstocked. not if his tank was compatible. smaller fish contribute little to the bio load compared to a larger or mid size fish. truthfully, depends on what type of filteration you have. if you have a large amount of media such as sponges in order for your bacteria to grow you'd be okay. your load is pushing it but its feasible.

Personally I think you are overstocked. Adding a Severum isn't the best idea, a cichlid is still a cichlid and will be more aggressive than you expect compared to other peaceful fish.
With those guppies you will be having a hard enough time trying to stop the babies if the water quality is good for them to mate.
The male betta will probably eventually kill the female, they don't cohabitat unless they intend to mate.
The lone penguin tetra isn't a great idea.
This stocking isn't the best and I highly suggest not adding anymore fish.

75 gallon
1 pleco
1 OB Peac0ck
1 Yellow Lab
1 Blue Peac0ck
1 Greshakei
1 Red Peac0ck
1 Acei
1 Chailosi
1 Flameback
1 Rock Kribensis

20 gallon
2 female bettas
6 emerald green cories

2 dogs Diesel and Hummer!

The original question of being overstocked is correct to ask, and i think that was answered by quite a few members........Your correct to think the bio-load from small fish is minimal at best, but what about stress from overstocked surroundings?........IMO, having your tank overstocked with imcompatible fish can give you a false sense of not having a problem........We all know some stressed fish will not eat when stressed out, ultimately leading to their death from starvation....If these same stressed fish are not eating, they are not contributing to the bio-load in the tank, thus leading people to believe everything is fine with there fish........What aboout the mysterious deaths that some people incur in there tanks when all there water parameters are fine?.........I believe that sometimes its the overstocked/imcompatible tank that leads to some fishes deaths..........Stress + not eating = death (that can be avoided)............Dont get me wrong, in the right tank, with the correct tankmates, and proper filtration overstocking is not that big an issue as some people make it out to be..........Choose the fish wisely and proper maintainance is the route to go with an overstocked tank...........
