Planted Piranha tanks?

  • We are currently upgrading MFK. thanks! -neo
I think the blanket statement of 'dim lights > bright lights' is not the proper answer to everyone.


But it applies to this thread. You just said yourself your caribe prefer dimmer lights.... I wasn't speaking for rhoms or any Piranha for that matter. Just a pygo shoal ;)

If I had a stunner rhom like yours id have him lit up too!


Also you can still use bright lites with Bw, kind of gives it a cool amber tone!

I think light preference may have more to do with a shoal then a solitary ambush hunter such as a rhom.

mine will adjust to high lighting but they prefer dim to no light, but I still want to enjoy them everyday and be able to see their beauty without compromising their comfort! This is where the combo of Bw and led come into play:

Obviously aquarium plants would be impossible to maintain in these conditions, hence the pothos. N03 35-45% decrease!

Ive never seen rhom in water footage where they were solitary. Wolves in th water even shows a relatively large group of large individuals. Not only were they grouping, they were very close.

I still dont think 'shoal' means low light. Nor do i think it effects all fish's personalities or comfort the same. If you want some serious no3 control floating and top water plants are definitely the way to go. But i still dont think theres any replacement for water changes. I have a rbp in a planted 40b that i DOSE the tank with nitrates, and other fertilizers.

Do we shoal rhoms in aquariums?

I'm saying IME with my shoal bright lite effects them NEGATIVELY AND makes them much more skittish (IT EFFECTS ANY FISH IN DIFFERENT WAYS)much more then my rhom, but equally they both can adapt to either or after some time. This thread is about the op's fish, which are a shoal...AND if he plans on maintaining lower amounts of aggression and having less deaths, then light, nutrition, water quality, space, decor, temp etc need to all be taken into consideration!


Now its about me being wrong about pothos or wc? I never said they were a substitute....read the thread you might learn a little bit about them instead of just automatically assuming I'm wrong again: http://monsterfishkeepers.com/forums/showthread.php?t=504763




Sorry OP for the thread derail, don't worry I won't come back here....

Lawlz, this isnt about you being right or wrong broguy. Its about youre idea that every shoal is going to behave the same under the same conditions. Im also less inclined to hanging **** in my tanks since my shoals have destroyed pretty much anything imagineable in a tank. Thats why i suggest a fast growing surface plant. Im saying to stop throwing out blanket advice to everything. Because In my experience, EVERY SHOAL IS DIFFERENT. EVERY TANK IS DIFFERENT. EVERY KEEPER IS DIFFERENT.

All these factors do effect aggression. I've never said you were wrong, and i usually agree with you, but those 'what if' situations happen all the time in this hobby. What if the dim light makes the shoal more active and that identifies the weak members to the shoal? What if the pothos rack falls in the tank an fish spook and jump when youre not home?

As far as shoaling rhoms, i am planning doing it in a plywood tank when I buy a house. I know a guy on pkeepers thats kept three in a 55 for months now with less aggression than red bellies would have. Rhoms are shoaled in this hobby. Not regularly, and not recommended for inexperienced keepers. ****, smoke has like a three manny cohab going on right now. Hes also got like 5 payara and 4 eigenmannis together. Unorthodox cohabs can be done by the right people.
 
most animal feel calmer under dimmer light but that doesn't mean they don't like bright light. piranha in the wild can be found in murky water with low visibility and low light penetration but can also be found in clear water with lot of light http://www.youtube.com/watch?v=S8qqTBwLJ68
pygos are in general more skittish, IME they behave the same with or without the light being turned on (as dim as a single 70W HM and as bright as 2x 3bulbs 36" T5HO). of course right after you turn on the light they will be all in shock for a little while but afterward there's not much difference.
in terms of cohabing rhoms, not gonna say much as I have neither the space or cash to make me feel comfortable at trying it out.
 
switching on the lights with a time gap would help in not shocking the fish. It quite natural too.

Get / make timers to switch the lights to ramp up the lighting towards midday and ramp down towards nights.

I have tried this , but not with a pygo tank.
