White stuff on Amazon Frogbit roots

Hi all,

Apologies for the highly technical thread title and for the newbie question....

I have just set up a tank 3 days ago, Tropica substrate with sand on top, a couple of rocks and quite a few plants, including some Amazon frogbit that I was given for free by my local fish shop.

I've just noticed that it has some white stuff on the roots, for want of a better term.

I wondered if anyone here has an idea what it is? Sorry the pics aren't particularly clear...

Thanks in advance!

Hi @fishandting, I've never seen that before on my Frogbits. I would take the "infected" floaters out of the tank and try and gently rub it off the leaves and roots - I would do it while the plant is submerged in a bowl of tank water. While it may go away by itself eventually, there is no reason not to take action given it's probably so easy to deal with just by cleaning it off - you don't have to uproot anything or otherwise disturb the tank.

Cheers,
Michael

looks like small amounts of fungus, likey where the roots were damaged . Wouldn’t really worry about it. From the photos it seems to me the plant is Pistia rather than Limnobium.

Thanks, I wasn't sure whether they were frogbit or pistia, or something else for that matter!

Thanks Michael, that's a good idea - I'll give it a try tomorrow and see if it helps

I agree with this, certainly from the first photo. And both are very prolific growers, so I wouldn’t worry if you break a bit of the roots off. I regularly deliberately snap off some of the very long roots my frogbit develops, and the plants are unaffected.

Yes, Pistia stratiotes. I wouldn't worry either.

I wonder if they are abnormal just root hairs?

Is it something like this? They concluded it was vorticella.

New tank what's this?

Doing a fishless cycle on a new tank plants are from my own tank except the floaters. Substrate is eco complete. Has been up for about 2 weeks and today I noticed white bugs everywhere on the glass, they're tiny. Also some fuz looking stuff on the floaters. Never had this. Did toss in some freeze...

Thanks all for the replies on this thread. A little update on the floating plant situation..... they got progressively worse over the past few weeks and are all dead now!

I'm wondering if there's any obvious reason why they didn't do well?

I've heard they don't do well with a lot of surface movement, which the tank has, as there's a built-in filter, but I've tried to divert the outlets so the flow is not too strong.

It's a Fluval Flex with the stock light, on maximum for about 8 hours a day.

Any input/advice would be gratefully received
 
Hi
Looks like it could well be some sort of additive damage to the roots.......Chemical or Fertilizer!
Then a secondary issue transpired?

Ah interesting, I hadn't thought about that. I'm dosing TNC Complete but hopefully that shouldn't cause issues.

I'm going to have to start again with a whole new batch of floating plants as they're pretty much all done for.
 
Could be the Fish Store dosed a water treatment for fish....a tad too strong and the result was damaged roots!!!
Only a guess though!!

You could try the light on for a longer time period, but I'd guess that it isn't light, roots or flow.

How do the other plants look?

Hey I wonder if the group might comment on this. This is fluval flex so high humidity under the lid. Could this lead to fungi growth?

Hi @Ghettofarmulous, I guess it's not impossible. Way in the past I've had fungus or mold growing on wires, sprayers, roots sticking out of the water etc. but I never experienced any fungus or mold on my floating plants. Currently, I have a 2-3 cm. clearance between the glass lit and the leaves (frogbit, ducweek and pennyworth) and its very, very humid under there.

Cheers,
Michael
