For the schooling experts

[Mr. Rain Cloud]

Good one.

To the original poster, you've already admitted your tank is overstocked, anything we offer about a "natural" look is just an opinion. i've discovered in the past people who ask questions like this tend to keep checking their thread until they hear the answer they want to hear. we can cut the chase if you just tell us what you want to hear.

You're spot on balli, I've had my tank for only 2-3 months and new at forums as well. But like you've also said, I just want to hear the experts' opinion on how i should go with the stock. Do I take out the rosy barbs to get rid of the overstocking problem? And if I still have enough room, without overstocking, add a bit more danios.

Your filter is rated at 340 gallons per hour unloaded with no head. Assuming you have media in it and your canister is on the floor you'd be lucky to get 70% of the advertised flow. Manufacturers use those numbers for marketing purposes. In reality, you're getting around 180-190 gph which is not enough filtration unless you stock your tank 1/3 of it's capacity. Canisters are great because they move water through a closed pressurized system, but they are expensive and largely inefficient compared to other types of filters. Add an AC100 or and emperor400 fir the most bag for your buck. Much cheaper and much more efficient.

That being said, roselines get 4-6 inches and need COOL water (70-75) with lots of flow for optimum health. If you do add a hob filter, you would still need to add a powerhead to run the flow lengthwise in the tank which your other fish would not appreciate. And they are schoolers so you need at least 4-5 for them to be happy. You might want to consider the fish you are trying to mix. Somebody is going to be unhappy in the long run. If your instinct tells you something is not right, then follow your instinct......

Just my 2 cents

Jc, my favorite post so far! Well, I've researched the fish I have and they all like coldwater, all are from around India and basically have the same water requirements(cold river flow and all school).

I actually do have live plants as well sunset hygro, wisteria, java moss, and rotala indica(all around India as well). Currently working on a DIY co2 yeast reactor and will add giant hygro after that's done. Using fertilizer for macro and micronutrients for now.

I'm just now deciding which to keep, the rosies or the danios since I just found out the actual inch per gallon rule and filtration issues which seems not to be enough. Thoughts?

The temp for all fish is the same but the flow for the rosies could be too much unless they are larger fish. The rosies are a backwater species and the roselines come from clear mountain streams. Nothing too drastically different , but if the rosies are smaller the added flow might not be appreciated. That being said, they can get 4-5 inches, but most likely not that large in a 75. It's not that all three species can't coexist, it's just finding the happy medium, for the roselines really like a strong flow as do the danios.

The good news is at reduced temps. your fish will probably grow more slowly so your tank size should be ok. but the roselines like lots of space as do the rosies. If it were me, I'd say lose the danios and boost the numbers of the roselines and rosies to 6-8 each. Add an ac100 and a powerhead moving water at the top of your aquarium lengthwise. Roselines will spend more time at the top where the flow is and the rosies will spend more time in the midwater and bottom areas where the flow is not. That would he a pretty cool looking display and you'd be around 7-8x turnover which would be just about perfect. Plus the ac100 would be easier to do periodic maintenance on, they move tons of water and can last forever, all for about half the price of your current canister.

Aquaclear's are on sale at Petsmart right now. The AC110 runs 500 gph, and has SO MUCH room for biomedia (especially if you cut the HUGE sponge in half lengthwise, and use the remainder for other things, like cutting a hole in it, and sticking it over the intake tube to protect smaller/weak fish.

 

[Mr. Rain Cloud]

Thanks for the info Laticauda. And Jc, I like your opinion.

Although I'm not sure about the additional powerhead since I do have live plants. It might be too much current for them to thrive?

 

[Laticauda]

An AC 110 on full blast has a pretty serious current, I don't believe an additional powerhead would be required. Just my opinion.

True. Plus with the plants it would be tricky. Either way the ac110 would be plenty additional filtration for that tank. Definitely best bang for your buck

 

[Mr. Rain Cloud]

Thank you very much, that really helps a lot!

I really do not know much about thses feeder fish..LOL............

I like rosalines.

Get yourself a new filter.

For natural, do you use gravel?
