Mine is about 19 years old and still kicking good. They outlived all other fish by leaps and bounds. Truly a great pet. Not necessarily from proper caring. Mine is built like a tank. Tolerates all kinds of water conditions, with air bubbler or not they are ok, although i see that they are happier with air bubbler. Tolerates many neglects and abuse. Even still alive with water temperature under 60f. Not happy though. Great first time fish. You just almost can't kill them!
The average healthy common pleco can live up to 30 years, but others (such as the bristlenose pleco) only live up to about 12 years.
They can live up to about 10 years if properly cared for.
--> I have a pleco that has lived in a 20gallon tank for 18-1/2 years
The normal life span for Plecostomus is about 10 years in an aquarium. The maximum lifespan of common plecos is not known, but is believed to be around 20-30 years in captivity.
A normal Plecostomus life span is 8-10 years. If your Pleco is really healthy, it may live for 15
years.
Mine in over 30yrs old
5-7 years.
no plecos will die
a catfish will eat any fish that is 3/4 its size.
Cold to a certain degree (no pun intended). Plecos can withstand a pretty wide range of temperatures as long as it is a stable temperature and if different from current slowly lowered. They do best however at around a 76 - 80 degree F range.
An Oscar needs at least 55 gallons, and common plecos can grow to a foot long - you must make sure you have enough filtration for this
No. Plecos are classified as herbivores or plant eaters. They are also bottom feeders.
"The Algae eating" catfish is a very broad term to use when asking this kind of question, though I'm confident you are talking about the Pleco(stomas). Yes they are from the South american rain forest.
yes
Goldfish should only live with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, or mystery/apple snails.
no
First: a "janitor fish" is what Americans call a pleco. Second: yes, you can keep a Betta (fighting fish) and a pleco (janitor fish) in the same aquarium. Plecos are only aggressive to other plecos, so your pleco won't eat the betta. The two fish live in different parts of the aquarium--plecos at the bottom like most catfishes, bettas at the top because they're airbreathers. A betta has the common sense not to mess with a fish as big as a pleco--and it wouldn't matter anyway because plecos are armored fishes. Plus, bettas love to eat snails so they are a good addition to your tank maintenance team. Now! This is the problem: Plecostomus catfishes get huge--if your fish isn't a foot long two years after you get it, you're not feeding it enough. (Plecos eat things like zucchini pieces that you weight down so they sink.) It is a fish that needs AT LEAST a 55-gallon tank to live and be happy. If you've got a small tank like a 10 or a 20 gallon (40 or 80 litres) I would get either Ancistrus catfish (like plecos but much smaller), Corydoras catfish or upside-down catfish.
The fins are larger on the sailfin...but almost all the "common plecos" (Hypostomus plecostomus) on the market are actually sailfin plecos (Glyptoperichthys gibbiceps).
You shouldn't expect the plecos to survive just on algae. Get some bottom feeder pellets for them. They need food. Also, that tank is much too small for two plecos, let alone six other fish.
