Re: Goldfish Fry #31
Thank you! Over the past few days I have been slowly transferring fish around tanks - one of my fancy goldfish was being chased by 2 others so he was in a separate tank for a few days as he was exhausted. The tank containing the babies needed a major clean, so I managed to move them into 2 very small tanks for the time being. Now my adult fish are back in their original tank with a carbon cube to help keep the water clear. I also bought a common Pleco today - mainly because I thought he was cute but my excuse was ‘to keep the tank clean!’
I am currently ‘baby proofing’ a 38l tank for the babies to have until they grow too big for that tank. I changed their food from flakes to liquid, as I did some more research and found that the flakes had too much protein for them to digest, so they weren’t eating enough of it to grow healthily.
Thanks again for all of your advice :)

Help bit of an emergency #32
Hi all,

I hope you’re well in lockdown.

I made a rookie mistake 2 days ago.

I have 2 guppies I think sorry I forgot the name and can’t find them. But small little fish in a 15L tank, I have a smallworld filter and pump.

2 days ago I changed the filter to a brand new one. Moron I know now.

One of the fish is fine but the smaller one is gasping at the surface a lot he’s pretty much living there and lethargic.

I took a sample of water to the store and they said the ammonia was at 1.

I’ve done a 50% water change just now and used a little ammonia remover, which I know isn’t ideal long term.

What else can I do?

How often should I water change from now on?

We’re all really fond of the fish and I know he’s really not well.

Complicated? #33
Hi. The problem I have is that I’ve lost most of my fish following treatment with praziquantel. Tank details: 200 litres, community tank. Heated to 24, filtered with a Hydra 40 (Maidenhead Aquatics). It’s been a problem free tank and is 8 months old, planted well and has a mix of kuhli loach, guppy, neon tetra and both red cherry and amano shrimp. Around 18 fish in total, 4 amano and a bunch of red cherry who bred very easily. Lighting 0700-2200 and all has been well. A couple of weeks ago, I noticed some of the fish brushing their gills against the tank contents, there was some fin reddening and fins had a feint white edge on some fish. Research led me to a diagnosis of gill fluke. Further research indicated over the counter treatments could harm shrimp so ‘Fluke Solve’ seemed to be the answer (praziquantel 50%). 0.8g was added a week ago... the following day I noticed the fish struggling a bit and within 24 hours lost a couple of guppies, this was followed by a kuhli loach and a number of red cherry shrimp. Over the last few days the death rate has been soul destroying. None of the neons or amano have died. I can’t find anything to reference regarding these problems with the use of fluke solve, the manufacturer is not able to advise. The treatment requires a second dose but I’m concerned this will finish everything off. Advice from local aquarium stores is to stop. Readings are the same as normal, PH = 7.2, nitrates = near to 0, nitrites = 0, ammonia = 0. As the fish remaining seem to be heading to the top a lot, I thought it must be low dissolved O2 as the problem. The filter disturbs the surface and I added an air stone to increase this. I generally rotate water changes with RO and tap water (treated) - 30 litre water changes every week with a bigger change once a month. I used RO with minerals yesterday as I’m running out of ideas. I have less than 10 fish left, only 1 kuhli left from 4 and he has red, sore looking gills and if he comes out briefly, swims erratically, towards the top. I have a black guppy with a fan tail, the edges are white / jagged and condition of the tail has deteriorated over the day. One other point, the plants in the tank appear to be struggling since the treatment too, some dying leaves on the java fern and crypt. Moss is thinning out and much more straggly. A lot going on I know.... any suggestions on what to do next would be gratefully received.

Re: Room temp / Sub-tropical nano fish tank #34
The link is also good for each species' water hardness requirements, usually cited in ppm (CaCO3) or dh (German degrees hardness). Check CaCO3 and German degrees hardness for your postcode to see which of the species are suitable, as well as the temperature and tank size required for each.

It sounds like you're planning on a silent/planted cycle with fish-in, rather than the more reliable and easier fishless cycle ... hless-cycling-article.htm
Silent/planted cycle with fish-in, from what I understand, needs the tank to be absolutely rammed full of plants like a jungle (in which case you'd probably never be able to find/see the fish), and also needs the fish to be added almost one at a time (which wouldn't work well if you went for a shoal of fish eg of endlers as they'd be constantly establishing/re-establishing their hierarchy every time a new one is added). If, however, you decide not to follow the fishless cycle method above, then it would be definitely worth having this to hand ... ammonia-nitrite-spike.htm for if/when you encounter problems.

Re: Room temp / Sub-tropical nano fish tank #35

Some of those won't be suitable either due to temperature or to the size of the tank. I suggest you check them on this site which is a very reliable source of accurate information:

Room temp / Sub-tropical nano fish tank #36
Hey All,

New to the forum and a fish noob looking for advise?

Recently purchased a 10-gallon tank and I've planted it with live plants and still trying to get my hands on a few more before I add any fish. A few plants have melted already :(

I want to stock it with nano-size fish (no more than 2 inches) but I'm looking for a variety of fish preferably non-schooling fish.

I'm guarantee going to purchase;
Red cherry shrimp / or Amano Shrimp
Zebra Nerite snail

But I'm stuck picking other fishes when I get to this point of a cycled tank.

I do not plan on having a heater in my tank so this narrows my selection down and I also prefer to get fish that do not school but I'm stuck on which fish do not require a school or a tropical waters - I've been monitoring my tank for a month now and it's gone down to a low of 18c and the highest 24 c.

Can anyone shine some light on which fish that can fit my requirements all year round, I currently live in London (I have a heater on standby for the colder months of the year if need be)

I've made a shortlist just not sure if whether they fit my needs;
Clown Killifish
Scarlet Badis
Bloodfin Tetra
Celestial pearl danio
White Cloud Mountain Minnow
Orginal Endlers livebearers
Pygmy Sunfish
Pygmy gourami
Chilli rasbora
Oto Catfish
Albino Catfish

I find my self cutting and chopping my shortlist daily and researching more and more but many sources mention conflicting information.

Any help would be greatly appreciated.

Re: Nano tank chilling #37
That should do the trick - very ingenious

Re: Newbie tank advice #38
A single male betta would be ideal. (However, I get the impression that they don't seem to be as long-lived as they used to be - a few years at best.) The 30L Bi-Orb you describe is best suited to shrimp, snails, and the betta is probably the one fish that would be alright in that environment. An alternative would be ... tropical-aquarium-black-2, PAH's Lovefish Panorma 40L or the Fluval Flex 34L or 57L or

Alternatively, a minimum 64L (60x30x30 footprint) tank such as ... k-64-litre-%28in-store%29 or ... 1hKghNEAQYASABEgKagfD_BwE would house a shoal of white cloud mountain minnows. The downside to having a shoal of fish is, if one/several become ill, it's often best to treat them in a separate tank with separate filter to prevent putting healthier fish through unnecessary treatment - and you may not be in a position to have this extra equipment.

If I were you, I'd go for the betta. I can't think of another fish that would do well on its own. Hope that's helpful.

Newbie tank advice #40
Hi, new here.

I’m looking at getting a fish for my daughter, I’ve only had goldfish before when I was a child and I’m sure I did much wrong.

I was looking at relatively easy to maintain fish. I’ve read a single male betta are easy to look after is this right? Or is there another type of fish that could be more suitable?

Also tanks and set ups, I’ve never had a tropical tank before so I don’t even know where to start.
Pets at home told me a biorb 30L classic tropical tank would be perfect for a betta but looking on here I see people are very against them. What is the best tank to get for a betta.

Thank you
