How much does a heater cost to run for a year, is it much above room temp?
Not really.
Currently set at 26c and isn’t on constantly. I’d be amazed if it’s more than a few quid.

Note that as far as the heater is concerned he says he is working on worst case scenario with the heater on constantly.
To have a more accurate figure you would need to monitor your own tank & see how often the heater comes on & for how long over a given period.

That’s all very interesting but the tank they describe is literally ten times bigger on every front.

Was an answer to dhutch's question so perhaps I should have quoted it in the reply.

To get a guesstimate for your own tank just use your equipment performance data instead of the one on the example.

Yeah ok, fair enough. It would be interesting if they had actually worked out the duty cycle of the heater, but obviously worse case being £1 day it's not ruinously expensive.

and so it begins...

Are you sure you have just one? wink
Well.....I was. Until today.
Sat for a bit just watching the Three Amigos and their new protégée wafting about a bit when something flitting about in the corner of the tank caught my eye.
Another littl’un, only this time absolutely tiny, still small enough that it was mostly getting carried by the current from the pump outlet. Ah well, another one made it, although it’s still small enough to get eaten - the flip side of that is it’s still able to get through the grate to the filter reservoir (where the big fish can’t reach it).
Flitted around for a bit then vanished. Must’ve gone and hidden in the back of the tank again.
Just lifted the lid and had a look.
Yup, he’s hiding in there alright.
Along with about twenty little buddies.
eek

Fish will only breed when conditions are right......so well done on that front......

Thanks. Must admit I’m secretly pleased smile
Two things:
How big until the new arrivals can share with the grown ups without being on the menu and;
What to do with the surplus? Can’t keep them all!
Or is it a case of safety in numbers as only one or two out of a couple of dozen will actually survive?

Sounds like the filter has protected them from being munched.

I think once they’re a few weeks old they are quick enough and small enough to be able to get away from bigger fish!

Surplus is a tricky one though, your local fish shop might be willing to take them? Ours will once they’re 1cm or so

More progress.....
About four of the smaller fry have now ventured in to the main body of water and are now just about big enough to not get eaten, and are also quick enough to avoid capture:

I never had any surplus problems in my 60L tank and about 6 adult Platy, on average only 1 or 2 made it to full grown adulthood from every batch of fry, as nature takes it's course with some not making it or getting eaten etc.

If you find yourself with too many reaching full size and overstocking, you could always advertise them on Gumtree as freebies, or you could start fish-less cycling a bigger tank along side this one and up-scale things in a few weeks!

I used to take my fry once they had reached a certain size to my LFS and swap them for RO water.

I got 4 fish for my 7yr old daughter and the following happened.

One ate the other 3, then got pregnant and gave birth to like a million little fish.the big fish then died. The babies all died apart from ONE, and that bd locust grew to full size and stayed alive for an absolute age, despite living in a green soup surrounded by death.

I was glad of the day I could lob the lot into the bin. the second most stupid idea my wife has ever suggested.

If you were wondering what the first was, we adopted a bunny rabbit and its the most pointless creature that ever existed, the kids were interested for all of 7 seconds.

Maybe they (the fish) just didn’t like you and killed themselves off out of spite?

So something crossed my mind today...
We now have eleven fish in the main body of the tank - three adults (approx 4cm long), one juvenile (approx 20mm long) and seven littl’uns all around a centimetre long.
Obviously this means there is now more waste being produced.
Coincidentally the live plant we have has gone mental, growing so fast it’s approaching being out of control.
Are the two connected? More waste = more plant growth.
Thing is, if I chop back some of the plant, will it upset the whole balance of the tank, bearing in mind the plant has appeared to prosper in response to sharing the tank with more fish?

Yes, they are.....Are you still using the original filter or did you buy an external, I forget ?

I wouldnt worry tbh, the plants will taking up the additional Nitrate hopefull, and your regualar water chnages will take the rest out - assuming your tap water isnt shyte like mine at 40ppm !

Exactly that.

Fish eat food, 'produce' ammonia. Super toxic to fish.
Certain bacteria eat ammonia, produce nitrite. Really toxic to fish.
Other bacteria eat nitrite, produce nitrate. Moderately toxic to fish.
Plants eat nitrate.

That plant growth, is helping absorb the nitrate, which isn't particularly harmful unless it builds up to toxic levels - that's why you do water changes.

It's feasible, with the right setup, to not do water changes at all - typically by using terrestrial plants growing in air being watered/ fertilised by the aquarium water.

As long as you don't go crazy with the pruning, and keep up the water changes you'll be fine.

Only with brackish/saltwater I thought?

I've grown Pothos out the top of a tank before - worked well and was fairly attractive.
