I got a 30 gallon tank that ended up with my 2 Upside down catfish with 2 black moor Goldfish... I am aware that tropical fish and gold fish do not mix, but I have large fish in my 72 gallon tank and they might end up as chow, or the Moor's fins would get nipped... that is the only other tank set up at the moment. So, they are going to have to deal with it for now. There is no heater and the temperature is around 21-23 degrees celcius in there.
I would like to add some more Upside down catfish but I dunno if it would be overstocked. I heard 20 gallons per goldfish + 10 per additional, with 30 being the minimum. One of my catfish is dominating the other, he/she (I think it is female, because it is bigger, but he/she might just get more food) pushes the other around a little and hogs the best hiding spots (they feel under the filter is the best spot) and the little one has to go inside a hole in an artificial log I have in there.
PS:I got 2 snails from a local pond and"quarantined" them in a rubbermaid tub with some other pond critters for a week or so, then put them in to deal with algae on the glass. Do they make any difference in the nitrogen cycle?
PSS: I am not getting rid of either of them. I <3 those moors, and I <3 my cats.
ANYWAYS, I know they are a shoaling species, I have seen the pictures... I want to add some more of them but I don't know their Bioload. I have had them since october '06, but always had only 2... I was pretty NOOBy then. I feed them "tropical fish flakes" at night because otherwise they would get no food. The tank would be planted but those moors dug up the plants I put in there and ate them. I tried duckweed as a floating plant, so I could get them to move to the surface like in the wild, but the Moors ate that too... I was planning to feed them mosquito larvae from there. Any suggestions? I would change the substrate to sand, but my goldies love to dig and forage, so they might get sick from injesting too much sand. Right now I have light blue "aquarium gravel." At least it is easy to clean...
