Pterygoplichthys scrophus

[sequoiacat]

Do Pterygoplichthys scrophus tend to like slime coats of other fish ?

[andywoolloo]

I do not think any pl*co would do that if fed properly.
What are you feeding him? Who does he live with? Do they
out compete him for food? How does his stomach look?

[sequoiacat]

that have it yet, i assumed no plecos would feed off of slimecoats unless improperly feed.

when i do get the rhino its tankmates would be angelfish, blackghost knives, and a bichir. its diet would be algae wafers,and anything else it would like.

I agree, if they are properly fed, they are unlikely to feed off the slime-coat of other fishes. However, if they get into a habit of eating slime-coat, they may not get out of that habit for a long time, even if fed properly.

This has been recorded for many different pleco species, from little otocinclus to large commons, and P. scrophus are close enough to the common variety to suspect that it will. But it's almost every time been recognised as a sign of starvation symptoms.

The problem is greatest with slow-moving, large-bodies fishes - fancy goldfish and discus has been known to be attacked.

Keep an eye on it, and if you start seeing round marks on the sides of your fishes, you know you have a problem.

i dont really reccomend ghostknives with big plecos-they will out compete them for food-this is too my experience-unless you have a big tank

the tank is a 120 and each fish will be target feed.

gallon or litres?

120 US gallon, I would presume from someone in America. Most American's wouldn't know a liter if it hit them in the face. I'm joking somewhat, but realistically, no regular consumer items in America is really sold in liters - except exotic imported stuffs at least - Coca-Cola and other soft drinks for example come in 15 oz (355 ml) cans, 20 oz (567 ml) bottles, 32 oz (946 ml), etc. Milk is sold in "quarts", which is 1/4 of a gallon, bottled water is in gallons (or the sizes that are used for Coke etc), petrol/diesel is sold in gallons, etc, etc. The US is very "non-metric", although in the long past they did make a step towards it when they defined a pint - it is 16 fl oz, which means that a pint of water is the same as a pound of water.

does great britain use metric??? i thought america would do to because english people settled there-i always thought any country at 1 point controlled by britain would use the metric system

[MatsP]

Technically, the UK is metric by law. But it's slow in taking on the metric system in practice.

When the US belonged to the British Empire in the 18th Century, the British Empire definitely was not metric. The units are called the same thing in the US as it was in the British Empire, but an Imperial gallon is slightly larger (as I explained in the previous post).

The reason that the British empire didn't take on the metric system early on was that it's french - the same reason we don't drive on the right. Napoleon influenced the rest of Europe to a large degree, but England being a) an island, and b) opposed to anything French, the metric system wasn't particularly well adopted.

And even things in metric countries aren't REALLY that metric. Why do you think copper pipes are 15, 22 and 28 mm? Because they are 1/2", 3/4" and 1" internal diameter, respectively.
Or plastic pipes are 32 and 40 mm? Because it matches 1.25" and 1.5" pretty well.
Why are plasterboard and plywood sheets 1.2 x 2.4m or 1.22 x 2.44m? Because they are (approximately) 4ft x 8ft.
Kitchen cupboards come in 30, 60 and 90 cm sizes - guess, what? That's 1ft, 2ft and 3ft (approximately).

In some supermarkets in the UK, prices are in £/lb rather than £/kg - probably mostly because it appears to be less than half the price...

yah sorry about that, thread got way off topic, it is 120 gallons, so about 454.25 liters. I personally think metric is better an more aqurate and easier to use in length,and temperature measurements, but for some reason i find volume easier in gallons and ounces.

we are sold some drinks in liters here 1, 2 , and, 3 liters of pop. but i doubt it is an accurate liter.

Metric may be better for distance and weight, but temp is best measured in dergrees Farenheit rather than Celcius. A F degree is a smaller incriment than a C degree. So you can get better temp control with a Farenheit thermometer. It may not be so be so critical with most fish, but when I bred reptiles all my European friends would use American themostats for incubators because they got a pretty big die if with the Celcius ones. The temp fluctuated too much and the eggs would turn (die).

But off the subject..... The US now sells bottled water mostly in 16.9 Oz (500 ml) bottles. I'm sure its to satisfy the export markets to Canada and Mexico, which are metric counrties.

And America didn't follow the other previously British countries to metric because we're not a member of the BCN (British Commonwealth of Nations). Also, we're still a bit stubborn from that skirmish a few hundred years ago.

But anyway...... Metric is great for measurements of distance, mass, and volume. But I'll always argue for Farenheit temperature. so our water boils at 212 and freezes at 32, but se la vie. (there's those French again)

A F degree is a smaller incriment than a C degree. So you can get better temp control with a Farenheit thermometer.

Interesting point. The "size" of a degree is indeed about 1 degree F = 55% of a degree C , however, that's only lines on the scale, or a number on a display. The precision of the thermometer or thermostat comes from more factors than the scale that is used to read/set it. I can get a thermometer that shows a scale of 0.1 degree C - which is almost certainly good enough for nearly everything. Thermostats are more complex to explain how they work and how the "set" temperature relates to the actual temperature [for good results, you really want something where the "actual" and "set" temperature can be calibrated], as well as the gap between "on" and "off" temperatures for a given "set" value - which is highly likely different from the scale of the "set" temperature, and for a quality product, this should be documented.
