Been a few months since I posted. I still have the same 125l tank, currently stocked with:
7 x harlequins (original set of fish, still alive, all bar the runt I posted about last year) 3 x panda cories (3 surviving out of an original group of 6 bought about 12 months ago) 3 x normans Lampeyes (3 surviving out of an original group of 6 bought about 6 months ago)
I've had a few ups and downs - mostly downs, with the casualties I've had. Focused on tip-top water quality over the last 6 months and ensuring my TDS doesn't get above 180 (remineralising RO). Everything seems stable now, and no more deaths.
I am planning on increasing my stock over the next few months as follows:
7 x panda Cories (I read they prefer as big a group as possible, so my aim is 10) 3 x harlequins (bringing group up to 10) 3 x normans Lampeyes (total 6)
I plan to do this over the next two months in 3 groups. Will keep the new ones in a quarantine tank, for two weeks, starting my tank parameters at London tap (as per water in fish shop) and then replacing at 10-15% every few days with remineralised RO to acclimatise the newbies gradually before introducing to the new tank.
My stocking plan gives me about 114cm of fish (max stocking capacity 122cm by my calculations). I was wondering how stocking works for shrimp - I'd be interested in Yamato shrimp, but I don't know how big a bio load they carry, whether it would be tolerable for a decent colony? Am I being a bit too ambitious?
Precisely. I already thought fish had personality and individual character traits. Watching the groups in my tank and (what I think) are pairings or trios going off and doing their slightly separate things is all the more fascinating (they were already really fascinating so I'm super excited now).
I'm so glad I made the decision to take up this hobby.
How harmful are daily temperature fluctuations to fish? My heater is set to 24C, and throughout the colder months my tank temp has stayed between 24-25C. However, now we are in summer and have had some very hot weeks, I'm seeing a daily temperature variance of 24-28C which is over the upper limit for the fish I'm keeping.
When I see things getting hot, I am leaving my lid open to allow the water to evaporate with a fan blowing over the surface (and it evaporates rapidly!!), but are these continual spikes extreme enough to cause any problems with my tank inhabitants?
I have pandy corys, harlequins and norman lampeyes.
Hi Fishlady. Thanks for the advice. It never crossed my mind that losing a few centimetres on each dimension could have such a dramatic impact on water volume - I've measure the internal dimensions and it does come out at around 125 litres.
I was using 110 litres as my guide for stocking but then I did the calculation on external dimensions as you said, and it came out much bigger than I thought it was, and was therefore very excited! I shall calm down now....
Hi everyone. I have an Aquamanta Eco 80 fish tank and according to the manufacturers website (here) the tank volume is 125 litres. However, using the calculator on this site it comes out as 160 litres. That's a massive difference.
I know that the calculator is correct (I've tried other calculators too that come to the same 160 litre answer), but that is an extra 35 litres to play with.
I'm right to go with actual maths rather than what the manufacturer states, aren't I? I don't want to end up overstocking...
Thanks SO19Firearms. I hadn't really thought a lack of nutrients would cause algae - I thought the opposite would have been true. I have a very low tech set up - in that I use liquid carbon! And my lights are on for only 6 hours a day.
Tackling plants and algae are the next thing I want to focus on once I get my parameters right, so I may have more questions...
