Adding a new fish

Post by jmcdonald »

Hello all.

I'm a bit of a newbie to the world of home aquariums as well as this forum. :oops:

I was wondering if anyone could suggest a good catfish for a tank that already has a:

- Gold Panchax
- Silver Molly
- 3 Black Mollies
- 2 Guppies
- 2 Platies
- Swordtail
- Flame Gourami
- Mystery Snail
- 2 Tri Colour Sharks
- 2 Red Tailed Sharks

Thanks in advance, :wink:

One very important factor in this equation is what you'd like... This is a personal taste thing, and I can't tell you what you'd like...

What we can advise you on is what size fish would go well in your tank - if you tell us what size your tank is. And of course, which ones go well with your existing fish.

Sorry for the lack of details earlier, my tank is 2ft long and 1ft tall.

I would love to have a Farlowella Catfish (as seen in the pic below).

I would also love to have a Polka Dot Pimelodella Catfish (as seen in the pic below).

Sorry for not putting scientific names, but I am not entirely sure on them.

Thanks in advance,
Jack :)

The first is a or something very close to - there's been several cases of long discussion about the correct identity of Sturisoma species - but they are generally pretty much similar in care and behaviour, so from that perspective you can look at the above species and determine what it needs.

I wouldn't recommend this fish in your tank, simply because the fisn grows to 20cm, and your tank is not big enough for such a large fish.

The second picture is a , and again it's not suitable for your tank - not so much because it grows too big (around 15cm, which technically is OK for your size tank), but because it's a fish that does best in a group of around 5-6 fish (or more). They also eat small fish, so for instance a male guppy would probably disappear at some point...

Thanks for your replies.

How about a Whiptail Catfish (Rineloricaria sp.)?
Do you think that would work well? Pic below.

The site I got the above details from, says the fish above grows to 5".

Or maybe a Banjo Catfish - Bunocephalu kneri (also according to website, grows to 5").

Thanks for your previous opinions.

They would be theoretically OK. Banjos do like sand though.

However you already seem to be stocked to capacity. What are you nitrate values before your weekly water change?

Sorry for the double-post, is it possible to edit posts?

Anyway, would a Spotted Raphael Catfish suit my tank?
The scientific name is Acanthodoras spinosissimus and I have a pic below (From PlanetCatfish)

Thanks in advance.

Sorry Racoll, I am sort of a newbie in home aquariums, it is only with help of friends, family and basic instructions on Ph and Ammonia test kits that this fish tank works well.

Well, one thing that I can say is you gotta watch size..
You got smaller fish that can't have bullies in the tank, and you can't have anything too big.><
{You could probably research mollies or guppies and learn what lives in their naturable habitat and stuff, then check it's temperment and see if it is sold in a store... if that helps at all..}
But yeah, good luck at finding something.!

And I believe the Rapheal is too big for your tank... {I shall let others answer though, mesa no expert}

Mickey, the website I found regarding the catfish said that the Spotted Raphael was only 4" big?

When I asked about the rapheal, one it's too big.

Two... they get mean.
I mean those things hiss if you take em outta water for too long... {kinda creepy how the pet store person knew this for a fact...}
Edit: Like I said before, I don't know 100%, I say wait for Racoll or somebody else to answer.><
I don't want to give you wrong information...

I'm with racoll, you probably haven't got much "space" left in your tank [and I should have said so in the first instance, really!]. It may not seem like you have a lot of fish in there, but the smaller the tank, the more likely you are to get problems caused by dirty water, and the more fish you have, the dirtier the water will get...

I would definitely not recommend raphaels with small fish either - same as with the Pictus cat above.

It's more of a croaking really. They sound like a frog. It's supposed to make you put them back in the water, but they didn't account for kids who kept pulling them out of the tank to amuse themselves! :roll:

The spotted raphael () gets to about 6" max, although they are slow growers.

Very cool fish, but you're lucky if you see them in a "regular" tank with bright lights. They're rather nocturnal.

How would I test the nitrate values?
You can buy a chemical test kit in most fish shops. They're about £10 in the UK. I don't know how much that is in AU$

pictus_man_77, they are actually quite placid. I was suprised myself. They seem to have a half tank each and keep away from each other. Suprisingly, the most aggresive fish is the Silver Molly.

Racoll, does Nitrate have anything to do with Ammonia or Ph levels?

Nitrate in itself doesn't (noticably) change the pH, but it's related to ammonia in the sense that ammonia NH3 is converted to nitrate (NO3) via an intermediate step of nitrite (NO2) by "good bacteria" in your tank.

You need a test-kit for at least:
Nitrate
Nitrite
Ammonia

Some of this you may only need to test once in a while, but nitrate is something you want to check several times a year (once a month or so) to keep an eye on how your water changes are working out - if your nitrate level is not "low", then you need to do more water changing, either more often or more volume each time (or both).

A pH test can be useful too, particularly if you live in an area that has soft water - because you can have something called a pH crash (where the pH drops from around neutral (pH 7) to really acidic (pH 4 or so) due to the breakdown of plants/food/waste in the tank). If the water is quite hard, it's probably got enough buffering capacity to keep stable, and then you don't really need a pH test kit - it'll just stick around pH 8 or so anyways...

Ammonia and nitrite tests will be useful for a new tank to see that the "cycling" (buildup of the above mentioned good bacteria) is finished - in a healthy aquarium there should be no indication of Ammonia and Nitrite at any time.
