Diffrent Colourfull Fish

[Fraoch]

there are pinned topics on different fish you could have in a coldwater pond but nothing on coldwater tanks.
the tank i have at the moment is in my signature. I used to have 5 mountain minnows but i suspect the fantails either ate them or they lived their 2 years and died. i also used to have 8 platys but 6 of them died a month or so ago for an unknown reason.
i would like some different fish, as i have had the same stocking for a few years.
the tank has been running for 6 years with no problems before the platys. It also might look overstocked if i add more fish but i am buying a new external filter, fluval 205 and i test it every 2 weeeks or so and doesnt seem to produce and ammonia or nitrite, i only have to give it a 20% water change every other month or so.

could i keep guppies in that tank or will the fantails eat them?
and what other fish could be possible?

thanks

guppies and platies are tropical fish and need much warmer temperture thn goldfish which my be why they died. A lrge goldfish will eat smaller fish like guppies that fit in its mouth. you could keep a few wetherloaches which re coldwater or maybe paradise fish if tank is in warm roomand/or you live in hot country

hi, i have moved all my platies to the tropical tank now but i am getting a heater for the goldfish tank. this is beacause i live in scotland and since the winter here is so cold this year i need a heater just to keep it at a slightly higher temperature. the tank, i reckon went down to about high 40s low 50s C.
i already have a weather loach and algae eater and since its a high tank dont have any more room for bottom fish.
is it possible to up the temperature in the tank over time to a temp. tolerated by both goldfish and maybe danios/betta/guppies/platies/paradise fish? (not all of them, only one or two species)
or is there room to get another fantail for the tank?
thanks

Why do you need a heater in goldfish tank if it is indoors? An indoor temperature that is comfortable(or at least liveable) for humans should be OK for goldfish which can often survive outside in frozon ponds. Lower 50s is fine for goldfish in winter, assuming they are not the seriously deformed extreme fancy types a few of which need warm water. They should still be active and eating, However if you have no heating in the room where the goldfish are you may indeed need a little heating to raise temp to 12-15C when it is very cold
Pardise fish are subtropical and can coexist with goldfish at around 18C. Forget about guppies,platy,betta etc -they need much higher temp around 24C' which is too high for goldfish.

Just thought I would throw this out there

I used to keep guppies with my goldfish in the pond (bear in mind this is an unfiltered, non heated outside pond). I put them in there to get eaten as I was trying to improve my guppy endler strain so that they were all one colour morph and males in my tropical tanks. I chucked the ones I didn't want in various food tanks I had and the pond to fatten up before trading to my LFS (I was supplying them 30 full grown guppies a week). Instead the population flourished even with 8 10"goldies and 40+ baby 2-3" goldies whom following the textbook should of heavily predated and destroy the population. I theorise that because the goldies were well supplemented with live foods (blood worms, tadpoles, black worms, daphnia, insects and earthworms) and varied flake diet they weren't interested in the rest.

The guppies survived the winter even though the pond froze over although there was a significant loss in population over this time (Guppies start dying at 3 distinct temperatures 14C, 8C then 4C but the strongest can survive at 4C). So Guppies are worth looking into. If you have some complex rock/wood structures with extensive vegetation (anacharis would be good) then this can provide a nursery for the young so predation is a minor worry as overall the population is sustainable. Platys can be kept at 14C+ although they should not be fed at low temps. My RCS lived in the pond muck at the bottom very well and I found a population of around 300 whilst cleaning out the pond in the spring a couple of years ago. Bear in mind RCS were introduced as a batch of 50 that I expected to also get eaten or die in the cold.

Goldfish should not be fed flake food when the temps drop below 16C and should be switch to wheatgerm based foods until 10C. If the temp drops below 10C don't bother feeding, as the fish metabolism gets so slow they can survive for months on their fat reserves. If you do feed them at below 10C you risk the food rotting in their stomachs and various illnesses associated with that.

Paradise fish are a bit too boisterous imo for them to be compatible with fan tails.

Weather loaches are heavily restricted in the UK due to it being an invasive species. I would not advertise the point you have one like in your signature unless you hold a permit. The platies do better in a larger group say 8 individuals

thank you, that is really interesting and i will bear it in mind
also when i looked into weather loaches before there is a species widely sold in shops as weather loach but are actually some sort of cross or different loach which is legal and i believe i have that one after looking at the photos.

Just thought i'd interrupt to say that I have some goldfish living in my outdoor pond and temperatures have hit 24 degrees C in the water during summer and it hasn't caused any issues for the goldfish or any of the other cold water fish in there. Presumably it's prolonged high temperatures that aren't good for goldfish rather than natural seasonal fluctuations which bring with them water temps of 24+ degrees C?

I will also tune in and say I kept goldfish in Thailand in a tank that was constantly above 28C and sometimes hit 34C for brief periods in the summer. Depends where the goldfish originate from as to whether they can survive the temps. If I took my Thai goldfish back to the UK and chucked them in my pond I am 90% sure they would not survive the winter and vice versa.

My goldfish live in an outside above ground pond and the main killer for them has been high temps with low aeration. But now the pond is under a large shady tree (has been for a few years now) and has a large airstone working 24/7 no more deaths. I tried puting excess guppies in with my goldfish (most of them over 30cm) but the rotten guppies out bred the goldfish and even ate my goldfish eggs and fry. So the guppies got shifted back to tanks and an old bath tub. Even thouh I live in central Queensland our winter temps can get as low as 1degreeC and I found that the only guppies to die outside in the unheated bathtub were males, the females just continued on like nothing was wrong. But then they had the advantage of first going outside in summer when temps where high and humid and got to gradually adjust to the new temps with the changing seasons.
