Goldfish: becoming cold water at last

I have 3 goldfish myself and I do not use a heater. They like it cold. It is 1 goldfish per 20 gallons. You will also need double the filtration. So for a 50 gallon you will need a filter for a 100 gallon tank and so on. Try this web-site: www.liveaquaria.com
It usually has good info on it.

I'm not sure I see an advantage to hooking up an AC hob to a UGF.
The AC is good for keeping the coarse and fine particulate matter off of the substrate and right into its filter media where it is a breeze to clean. If you connect it to a UGF, all the coarse decayed material is going to be trapped in the substrate, which you will have to clean regularly and the AC filter media will be doing basically no mechanical filtering....which it excels in doing.

The last time I messed with a UGF, I had a 200gph reverse flow powerhead with the main tank filter being a Fluval 404. I envisioned the muck getting pushed up from the substrate and getting grabbed by the fluval, but eventually the UGF was more trouble than it was worth. It just wasn't efficient, and the powerhead intake needed to be cleaned too often, so I scrapped the UGF completely.

Also, my experience with fancy goldfish is that they mouth anything they come in contact with, so any non-fish inhabitants may not be eaten, but could suffer from constant harrassment.

lets not talk about filtration i have that covered and i have had success with an HOB connected to a UGF. please refer to questions above.

Ok, I was hoping to gain some new knowledge, as I've never heard of this before.

4) Plecos (as in L023 & L024) are tropical, not cold-water. They probably prefer around 75 degrees.

so my questions are:
1) is it safe to use sand with goldfish?

Answer : you can get away with it, but goldies are very messy. It is advised to have 10 times per gallon of fitration. SO on a 55 gallon, you want at 550 gph of good filtration, mainly mechanical and mostly biological, charcoal is not really needed unless trying to clear of meds.


2) how many more goldfish can i add to my existing 6-7inch and 3 inch one?

Goldies need at LEAST 10 gallons per fish and preferably 15-20, so you do the math, plus the room for any addtional fish you want to add..which not many are reccomended for goldfish

3) can i add the four dojo loaches?

Are they dojo weather loaches, then yes


4) is the pleco okay to leave in?

Answer, only if it is a rubbernose or bristlenose. Those are the only two that are truly advised.


5) should i add any other decorations?

Only if you take into account the dispersity of your water and how many gallons are actually in there per fish.


6) what other non fish can i put in it?

??? If you have 3 goldies, the loaches and the pleco, you don't have much more room.


7)what is the general gallon to goldfish ratio?

Answered above.


8) what temp to they thrive in?

Depends on what type of goldfish, fancy varieties prefer arouund 74-76

And I don't know what you mean by bubble brain...and what kind is your other? That will help me answer better.
