Filter for 70 litre Tank

ac82 · Post by **ac82** » 07 Feb 2006, 20:52

I have a 70 litre tank which I want to use to house a trio of Cory Barbatus, do you think this filter will be ok? I do not intend to have any other fish in the tank apart from the 3 corys.

Hi there,

Why 3 fishes (they aren't called Corydoras anymore, but Scleromystax Barbatus

), they are fish who live in groups. (like 6 or more)

bye Martijn

i read in the article on the barbatus that the males were agressive towards one another if the tank wasn't big enough. My tank is only 30" long so I thought I could only keep one male and a couple of females. Would it accomodate 2 males?

p.s. is the filter ok??

This is what i see, when i click on your posted link, so i do'n't know what kind of filter it is:

you should be fine to keep at least two pairs of in that size tank, although the catelog suggests they are fiercely territorial I have never witnessed this sort of behaviour myself.

In any case this happens only when the fish are ready to spawn, so if you do get a couple more and they ever start to fight, then you know you must be doing something right

For filtration, one of those filtes that hangs on the side of the tank should be sufficient provided you keep up the water changes. Personally I am not a fan of thermo filters, simply because if there is a problem with either the filter or the heating element then both are out of action.

A cannister filter might be considered overkill for that size tank, but is by no means out of the question. Generally it's better to over filter and good quality equiptment will last for many years and tanks.

good luck and let us know how you go.

I have to disagree that this is would be overkill. I run 2 Fluval 404 on my 75G tank. As well as a the largest Emperor BioWheel filter, a UV light and UG filter attached to a AquaClear Powerhead 101(I think thats the number).

At the same time my fish are a lot larger and generate more waste than 3 corys would.

If you want to talk overkill then you may consider that I was running those 2 Fluval 404s on a 40G tank. Never seen clearer water before though.

This is the correct link - it's just having a spurious

added to the link.

The filter looks OK to me. Nice idea to have a small internal filter with a built in heater. Of course it also means that MTTF [1] is somewhat lowered - if either the heater or the filter stops working, you'll have to replace "both" at the same time.

I'd probably go for the 120 liter version - bigger filter is always better... Being only 3 quid diference, it's not much money to argue about either...

Cheers for amending the link.

I already have the Hydor EKIP 350 which I used to use as well as an undergravel filter. I wanted to use sand for the barbatus and scrapped the undergravel filter. The tank will only have the barbatus in and hopefully a few youngsters given time.

As for the possibilty of anything breaking, I have a spare heater which I use to heat water prior to water changes and a spare filter so I have back up in case of an emergency.

On a separate note, I was let down today for getting some barabatus, anyone got any they wish to sell?

I use the Epik 350 on my BN spafning tank, as MatsP said, a good idea. My only issue with it is, the sponges block up very quickly and need regular, quite thorough, cleaning. As they are quite thin/small, this tends to kill off alot of the good bacteria. To combat this I use a fluval 1plus to boost biological filtration.

Of course, my problem could come from the number of BN fry and the amazing amount of poop they produce.
