Bottom feeders don't "count"
Posted 23 June 2003 - 02:12 AM
She said that bottom feeders; cory cats, plecos, etc. don't count in that number and I was wondering what the thoughts were on that here? Sure, they're not in the swimming space of the other fish; however, they are still in there and even if they clean up the gravel a bit, they still produce waste themselves? I was confused (not hard to do).
It would be awesome if they didn't count as I'd love to have 4-6 of them rather than 2. I have a 55 gallon and it's long, so there's plenty of bottom space for them. However, I don't want to overstock my tank either.

You will find that there is a great deal of disagreement on this forum, not so much as to whether or not bottom feeders "count" at all (so, if you have all bottom feeders you can keep an infinite # of them in any size tank? I think not! ), but as to whether or not the inch per gallon rule is a good rule of thumb or a ridiculous bunch of hooey.
My opinion, and I am only giving it here because no one else has jumped in yet (well, I see that while I was writing this you did get some answers, but I'm not going to change this whole thing now -- we all seem to agree anyway), is that "it depends". First of all, of course they count. Many bottom feeders grow to be quite large fish, and from what I have heard, many are also "messy". Granted, cory cats are worth their weight in clean-up detail, but as you say, they do produce waste just as the other fish do, so although their total 'bio-load' may be less than a fish of similar mass that simply eats what floats and poops, the bio-load does exist, so saying they don't count is silly (no offense to your friend)
To my thinking, beginners are told "one inch per gallon" like it's our mantra simply because they are less likely to overload their water chemistry (which is not fully mature for about six months) if it is emphasized that overcrowding is a bad thing. It takes time for the nitrifying bacteria to develop, and more time to "catch up" every time you add fish, plus the fish are growing, and it is keeping up with that, and so forth.
On the other hand, lots of more experienced fishkeepers have crowded tanks, especially those that breed, like CM. They increase filtration, have lots of healthy plants, test their water regularly, do extra vacuuming and water changes, whatever they find that it takes to keep their particular fish happy and healthy. Different fish have different needs, and someone experienced will know that and act accordingly. 8)
The beginner generally will have a difficult enough time getting his/her tank parameters stable and at acceptable levels and keeping them that way until they've been at it a while to really spend a great deal of time/effort learning the idiosyncrasies of a bunch of different fish, which is why fishkeepers tell them to get hardy fish -- so they don't kill them off right away and get discouraged.
So what people will ask you is, what other fish are in the tank? What kind of filtration are you using? How often do you do water changes, and how much do you replace? Do you have live plants? What are your parameters? And so forth. Then they will either tell you that you can have ten cory cats without a problem (jk--lol) or that you may need to add a second filter or do more vacuuming or add some plants, something like that.
So the good news is, corys count, but you can have more, if you're willing to take the advice of whomever comes along and provides it.

Just to add my two pence worth.
Any fish will produce ammonia, from its gills and it's urine. Yes fish pee. Fish poo will produce ammonia when it breaks down, if it left in the tank. Any fish in the tank has to be counted in a stocking calculation.
Another thing to take into account is not the qty of fish inches, but the fish volume, i.e. 10 inches of guppies will produce a lot less ammonia than a single ten inch Oscar, yet according to the inch/gall rule they can be housed in the same tank volume.

I received the answers/input/opinions that I thought I was going to receive. I couldn't imagine "not counting them", but I was hopeful at the same time. lol!
I go by the inch of fish rule loosely. I have a 55 gallon that has been set up (and cycled) for 4 1/2 months. I have:
1 large Angel
3 New Guinea Rainbows
2 Bosemani rainbows
1 turquoise rainbow
2 male swordfish
2 male dwarf gouramis
3 baloon mollies
2 cory cats
1 pleco (which I bought knowing I'd be getting rid of him later. "rid of", I mean, donating back to the store).
My Ammonia is 0, nitrites are 0 and nirtrates are 0. I do 20-25% water changes with vacuuming once a week. I have an aquatech power filter. I was thinking of getting another filter to add to it, but wasn't sure if that would be too much? My tank "kit" was from Walmart and I had read that it wasn't all that great???? Thus far it's been fine....
I have one live plant....
Anyway....... I calculate my fish based on their adult sizes not their current sizes. Although I must say I get alot of different reports, so size.. we'll see!!! Like the rainbows I read are 3 inches, but some other sites I read they get to 4 or 5! Hmmm?
Thanks again for the input! I appreciate it!

No, my friend isn't a cichlid enthusiast. Please don't misconstrue the post. It isn't a do they count in life, it's do they count if one goes by the inch of fish per gallon "rule". She is a fishy lover and have 4 tanks (non-cichlid actually).
We got on the subject as she's setting up her 4th tank right now and we were discussing stocking options. She said she wanted to add a cory, just one. I had read that they school and would be happier with at least two........ of course, having said that, could start a whole 'nother topic.
I've learned when it comes to fish, everyone has a different opinion and what works for one may not for another. Someone told her that they don't count, so she took that as "true" and passed on that information to me. She has over the years only had one in her tanks and they did fine, so ..........
I like to read what the majority tends to think and go from there.......

If you are going to add corys please add more than two,they prefer to form large groups so i would recomend at least 3 and prefferably 4 to 6,and they will need food of there own and will suffer if left to just scavenge.
Jamnog your right i cant stand livebearers,nothing worng with them its just a personal thing and i always stay out of posts concerning them,cichlids are growing on me and i now have a few,and even plan to start a breeding program with Malaiwi eyebiters eary next year.
Tanked,did you get your pictus cats? If you havent got them yet get 3 instead of 2,when kept in a group they will be a lot more active and wont fight as much.

I do feed my corys and I feed my pleco too. Although that's sometimes hard as my Angel loves those algae chips and swoops them up pretty fast. I have to distract him. ha ha.

I have a deep respect and passion for ALL fish!! In the past I just didn't keep them. I have my favorites and my not so favorites.
Since expanding my stock list to include tropicals I have come to enjoy a variety of different species.....cories to be one of them.
I still have 20 or so of the C. julii in stock and may decide to keep them for myself. I also just brought in 50 Pimelodus angelicus. FANTASTIC little cats. Always active and when food hits the tank....well reminiscent of the movie "JAWS"!!
They twist their bodies in all sorts of ways to catch a piece of flake or frozen bloodworm that may be passing them by.
I will probably never bring in live bearers (much to the disappointment of Les ), because, although there is a market here I cannot compete with the bigger wholesalers in price!!
I am curious as to the cichlid society you refer to...not to start a war, but because I know most of the reputable ones and they are fish lovers first and foremost and would never bad mouth another species of fish.
As to the original question of stocking yes all fish are to be considered when figuring the total bioload of the tank.
A very easy way to think of it is this......a pleco by some is considered a scavenger (although with the L# being anything but. These are very specialized feeders)would not be calculated in the total bioload, but when you look at it realistically a pleco is probably one of the MESSIEST fish there are!! I would even go so far as to say a 12" pleco can out poo a 10" oscar and believe me I know!!
Those 10.5" goldy plecos I brought in....well I have one in a 70 gallon tank and this thing makes a daily mess of it!!
