Quote from: Jon on Yesterday at 05:14:59 PMThe colour difference is probably due to them being different species. There are at least three sold as 'rummynose tetra' found in the hobby. These are Hemmigrammus bleheri, H. rhodostomus and Petitella georgiae.

I found that out after I had bought them

As to the Corydoras I can only go by the, now four, Corydoras I have at present although I have seen the same over the years. The gravel I am using is sixty years old at least and some of it even has some shell fragments in it

As Jon says for most plants you wont need anything but I found that Crypts grow a lot better with something in the gravel. Years ago I used potting compost below the gravel to lock it in but there are a lot of new stuff on the market you can use. If I had thought about it I would have put it in mesh bags and it wouldn't be all through my spare gravel that I am using in new tanks

Quote from: Fishtales on Yesterday at 03:00:40 PMI have only found this to be the case with newly bought fish. The barbells eventually grow back and I haven't seen any wear on my tank bred ones. I am assuming that is because mine are on gravel and not a bare tank which I think breeders use.

My experience has been somewhat different. I've come across many fish keepers who's Cory's have suffered from bacterial and fungal infections. You ask what substrate they're kept on and it's gravel... Or more specifically the 6mm to 8mm pea gravel that is so popular in the hobby. This stuff has sharp edges and as Cory's spend half their life digging around in it their barbels can be damaged resulting in infection. If you can find small and smooth gravel then that should be ok. But sand will be much better for these fish.

Ian Fuller is probably the world's number one expert in Corydoradinae Catfish. He runs a huge Facebook group called Corydoras World. The subject of gravel comes up often there with scores of people reporting problems due to sharp substrate.

Be careful when buying these. My first shoal were red and it extended towards the gills. They were peaceful and kept, more or less, to themselves. They died off, old age, until I only had one left so I bought another shoal of six. I didn't notice the difference until they were beside my original one. They are more an orange colour and only on the front of the head. They seldom leave the bottom of the tank and only take sinking food but they are very aggressive towards my Corys and are forever nipping their dorsal fins. The Corys with the other shoal were always out at the front of the tank, now they hide in the plants and only come forward when the food is put in. As soon as the Rummy Noses come near they shoot back into the plants, they are the same with my Plecs.

Just regular silver sand will be fine. Though there are companies like Unipac that offer sands in different colours so maybe have a look and see if any catch your eye.

There are a plethora of different substrates aimed at aquascapers these days but these are really for people who's focus is on the aquatic plants as opposed to the fish.

With the species I've listed you don't really need to go to that expense. You could add a few root tabs if planting Amazon Swords or other Echinodorus species but that's all you really need. Just add a liquid fertiliser as per instructions and you'll be fine.

That is brilliant Jon, thanks. I'll take you up on that kind offer.

What would you recommend for the substrate?   I see some of the YT guys use sand capping a nutrient base layer.

Quote from: Wildfisher on Yesterday at 02:22:13 PMStill have not decided whether to plant up the new tank or not. I'm way out of touch with species etc. Any tips for a variety of straightforward plants, best substrate etc?

Your tank has what is called 'low tech lighting' so with that in mind you want easier species. These are :-

Anubias barteri. There are a number of cultivated variants. All will be ok.
Jave fern (Microsorium pteropus).
Java moss (Vesicularia dubyana.

None of these species have roots and all will need to be tied to rock or wood. They an all tolerate low light and are very hardy with tolerance to a wide range of temperatures and water conditions.

Amazon swords (Echinodorus bleheri)
Cryptocoryne wendtii
Egeria densa (Elodea)


All three are also extra easy. The top two have roots and will need to be planted. You can do the same with the Egeria though technically it's a floating species. There's also Hygrophilia polysperma sold as cuttings. Strip the bottom leaves off the cuttings and plant in sand BEFORE filling with water. This will grow rapidly and you'll be able to take your own cuttings in no time.

The above are all a bit of a cliche but with good reason.

If you're wanting something a little more exotic but still very easy then consider any of the following.


You could also consider a lily bulb (You'll only need one) like Nymphaea rubra to add a splash of red colouration. The grow well and look great. There are also green variants.

Aponogeton natans. These are sold as small, crappy looking bulbs that grow like triffids and will flower with small white flowers at the water surface.

Any of the other large Aponogeton species with the exception of madagascerensis (Madagascan lace plant) as these are not easy.

Nymphoides Aquatica aka banana plant. Google it. It's a bit of a novelty but they're attractive and easy enough.

If you DM me your address when you're ready I'll post you some suitable species gratis.

Quote from: Wildfisher on Yesterday at 02:57:24 PMThanks Sandy. Yeah I have been watching that guy's videos as well as his mate from Maidenhead Aquatics. They can be a tad irritating, but seem to know their stuff. 

I agree on both counts. Matt is only starting out doing YouTube full time and I think he is trying to find his style and ATM he is trying too hard

Fire away. Grab the master test kit now and plant up BEFORE filling with water and you'll save yourself guess work and hassle.

If you do have hard, alkaline water coming out of your tap you will have deal with that before adding soft water species.

Oh and I missed a really important 'accessory'! You will need to cycle the filter so that it contains the necessary bacteria to break down fish waste.

This stuff is brilliant and really does work instantly. Spending a few quid on it would be very wise to prevent 'ne tank syndrome'. It also avoids introducing unwanted pathogens when using filter media / water from an established tank etc. Rams are not the hardiest species so avoid a 'fish in cycle'.

As I said in the other post have a look at this guy.

While not disagreeing with Jon just a few observations over the years.

'Gravel isn't ideal for Corydoras as it can damage their barbels. I'd strongly recommend you use an inert sand. This will help plant growth.'

I have only found this to be the case with newly bought fish. The barbells eventually grow back and I haven't seen any wear on my tank bred ones. I am assuming that is because mine are on gravel and not a bare tank which I think breeders use.
