Can anyone give me a rough estimate of how many fish i could keep in an 27.5 gallon tank?

Hi Steve.:wave:

It is not easy to calculate the number of fish in a tank. It would be best if you submit the stocking plan so we can sort that out as most of the fish depending on the size produce different amount of wastes. Some species may have the same size, but most tend to produce a lot of wastes than others.

27.5 inches of fish and this is at their final adult size. There are fish that you can out a few more and some you should put a few less in but your over all stocking plan should follow this "rule". A heavy planted tank changes this, heavy feeders like plecos reduce it and smaller fish like neons and some tetras increase this number.

Like Blue said, if you know what type of fish you want we can help you get the numbers you need and hopefully avoid too many.

I have trouble with this fish per inch thing, it sounds like you mean one fish per gallon of water, which seems low to me, sorry to ask but can you dumb it down!!

Ok, at the moment in my tank I have 1 panda cory, 6 neon tetras, and 2 clown loaches, am just worried about overstocking, I want community fish, like tiger barbs and mollys and the like, nothing to big, do you think that would be ok.

Clowns shouldn't be in the 27 gallons. It's far too small for two especially when in a few years, they will take considerable growth. Clowns can reach 12 inches and possibly more in the wild. We have one member here who has a 7 inches clown. 2 clowns are best kept in a 60-75 gallons.
You should add 5 more panda cories. They like company.:)
I wouldn't go over with tiger barbs. In that tank, fin nipping is highly possible. Go over with harlequin rasboras instead.

Wider bodied fish, such as angelfish, discus, etc. should be stocked at least 2"-3" of fish per 1 gallon of water.
Whoa! That's backwards, nu? 1" per 2 to 3 gallons of widebodies yes?

Everyone has missed the most important word in the "stocking rule". It's 1 inche of ADULT fish... always figure adult size from the beginning so they have room to grow. Most healthy fish will grow fast, and that's where a lot of people run into problems. Most fish sold in LFS's are babies, so it's rare to see them at adult size (with a few exceptions) and its rare that anyone puts an adult size fish into a newer tank.
I agree about avoiding tiger barbs, but I've raised mollys and neons together a few times, and they did well so long as the tank was heavily planted. If you can find them, coral platys are good with your mix. They're a dwarf species of platy, bright orange, and active. They're livebearing like mollys, standard platys, swordtails and guppys, so be sure to keep the breeding under control and don't pair them with 1 male/1 female. In a tank of that size, I'd suggest all male, or 2 females for each male.
Dwarf neon rainbows would also thrive in that tank. White cloud and gold white clouds would also thrive, as would glowlite tetras and gold tetras, green fire tetras, or even badis badis (the scarlet badis are awesome and super colorful with the males).
You have a lot of small options available. I'd get a list from your local LFS to see what of these they have available, and then work on how many of what kind. I notice the price and availability changes according to location.

Dawn's, as usual, right; stock for your adult size.

That means you're already overstocked with the clown loaches (as has been pointed out - but I do have a reason for bringing it back up.) The easy way out of this is to take the clowns back to the LFS and turn them in for a different loach. Striped (Botia striata, aka Zebra, Thin Lined. 4"), Yoyo (Botia Almorhae, aka Pakistani, Botia Lochata, Lochata Botia 6"), and Burmese Border Loaches (Botia kubotai, aka Polka Dot, Angelicus Loach, 5") are all attractive, engaging, and chow down on snails. They also like to be in a group of 3 or more (as do Clown Loaches) or they get skittish or sullen or nippy.

Another loach you may run into is the Skunk Loach (Botia horae). The stripe on their back? Not why they calle them Skunks. Very nippy and aggressive.

If you do decide to get different loaches, definitely check out the Loaches.com Species Index. I do love me my loaches.

Should be Botia lohachata although that scientific name is old already with Botia almorhae as the current name.

Yep. They are very aggressive. I used to have one and it has a tendency to chase other fish. Botia morleti is the new name though so Botia horae is no longer considered new.:)

Somebody did remember. Sorry, had to boast, won't happen again. :wink:
Anyway, the smaller loaches are really cool if you have numbers of 3-4. I have skunk botia and they chase each other around and fight over snails when my populations gets too high and I throw them in. I am just wondering with a 27 gallon, 3 loaches and 6 corries if there isn't going to be some serious competition for territory. My sunks chased out my cories from anything they wanted until I moved them out into their own tank. Maybe with plenty of small hiding places all will find their spots and be happy.

With a group of corys in the tank, why would you need the loaches? When setting up a healthy situation, it's not wise to get all of the fish that will inhabit the same territory, eat similar foods (loaches, while snail eaters, are also scavengers), and invade on each other's territory. It makes more sense to me that getting different groups of fish, who all perform different functions, keep different territories, and don't have to fight for it (or food) would be the sensible way to choose them. Bottom feeders, mid level, and upper level, are the 3 territory ranges in your tank. There are a lot of options to choose from, peaceful and colorful, and small enough to stay in that size of an aquarium.
To be compatible with the neons, you'll need something that stays small and peaceful, and some of the loaches mentioned are going to be anything but peaceful once they mature.
The smaller species of mollys, such as black yucatan, gold dust, and sphenops are all good. For bright color, coral platys are great, for tetras, von rio tetras and green fire tetras are both awesome, colorful, and peaceful, stay small.... do some research, find fish that are appropriate, and make sure they're available.
I found out that in helping someone from Iowa with the same situation, when I suggested badis badis for her tank, she fell in love with pics of them, but her LFS had never heard of them and didn't have them available.
As was already suggested, go to the LFS, write down names of fish that appeal to you, and then if need be, come here and ask us about them. That's what we're here for.... to help. Research what you find at the LFS rather than choose the fish before you know if they're available. Sometimes, if you ask, they can special order for you, but again, that depends on the LFS and where you are located.

Eddie, I couldn't have said it better myself, thanks for posting that. I only contributed because I wanted to make sure that "the rule" was not misinterpreted initially. I have preached everything you said to many many people over the years.
One suggestion I have offered in the past, for those who still don't "get it" is to take the adult size of a fish, measure it out on a piece of paper, and cut it out. Hold the cut out fish next to your tank, and common sense SHOULD take over from there.
Something else to consider when stocking is tank dimensions. A good example would be an oscar in a 55 gallon tank. The amount of water isn't the problem, it's the width of the tank. Once that fish gets beyond 6 inches, it can't easily turn around because the tank is so narrow from front to back. Put that oscar in a 75 gallon tank, and you're making a world of difference. The 75 gallon is the same length and height as the 55, but much wider/deeper.
Another common problem I see is the hexagon shaped tanks. A 35 gallon hex tank will hold different kinds and sizes of fish than a standard 30 - 35 gallon rectangular tank. Some fish need the length to pace, some fish tend to need height more because of their habits. Angelfish do better in a tall tank, as do gouramis (upper level dwelling fish), but fish like pictus catfish, irridescent sharks, bala sharks, etc. need the length to pace. It's always important to know the dimensions of any tank before selecting the fish that will inhabit it.
