Brand new to freshwater fish keeping! pics

  • We are currently upgrading MFK. thanks! -neo
I didnt know that. Well in that case, @fishboobs, I'd suggest staying away from rays.
 
Dont want to come off as mean, but i sure hope you have plans for an upgrade in the nearish future with all those fish...

Most rays from my understanding require tanks with a much wider footprint than a 100 gallon can provide...

No point in keeping a fish in to small of a tank. I can re-home him when needed.

Thats a great first effort, like others say tho there is a good chance the oscars will be too much for a 100g when they are fully grown without the ray!-) oscars have been known to reach 18inch although 13-14 inch is more common. im guessing when you say you set it up 3 days ago you mean added fish as it should have been set up for a good few weeks and allowed to cycle?

It really is one of the best newbies tanks ive seen though, and keep up with them waterchanges as rays need pristine conditions or you may lose him her.

I was under the impression a 75g has been noted as a great size for an oscar. Some even suggesting 55 ( which I think is way to small ). If they have the room to move around freely, isn't number of them just going to equal more water changes not tank size issues?

I cycled it over night. Used eco-complete with some seeded sand. I also used a combination of Biospira and nitro-zen bacteria additives. Put some large gold fish in and once I got nitrates ( the next day ) it was ready to go!

I believe the ray is a converted ray. In other words a ray that was originally saltwater fish that has been acclimated to freshwater. Unfortunately because of that the ray's imune system will not work as well as it would in saltwater. Most converted rays never reach adulthood in freshwater. If you want to keep a ray I sugest potamotrygon reticulata or potamotrygon hystrix. These rays are very small, the males rarely exceed 10" in disk width. You would still have to upgrade later on but at least you could keep the ray for a long time.

I'm pretty sure it's a converted stingray otherwise it's illegal. Freshwater stingrays are illegal in texas

The ray has been in freshwater since born. LFS said they've had great success with keeping them in freshwater for extended amounts of time.

I would be really interested in the white and black stingrays! If I ever got one I guess I wouldn't be able to share! ;)
 
if you keep them in good conditions and increase water changes as they grow accordingly its doable, as the oscars approach 12-14 inch their bulk will increase massively and so their waste, the nitrates will start to rise very quickly between water changes then their enviroment would start getting unstable... a drip system would be the best way to go rather than water changes imo.

im trying to give good advise when im guilty of over stocking myself but you gotta let people know the right way to do stuff, right? i have seven large growing cichlids, a medium catfish, large catfish, and two large growing plecos in my 300g... 60-70% per week water changes for me, im planning on a drip system myself!-)
 
^ seriously?

You're advising someone who is over-stocked to add an aro? And to a tank that cant hold one for any significant amount of time?

Back to the OP, im curious to know bow long the rays at the store survived in Fresh?

Since most of the time i've seen stores use that excuse, fish die within a couple of months to a year at best..

Nice tank...

It is true you can overcome overstocking with more water changes and more filtration to some extent but you have some heavy waste machines there!! lol

The ray you have is a converted ray and can be VERY difficult to keep in fresh long term, there are populations in the wild that live in fresh so it is theoretically possible but that being said not only may it stress easier but from what i have read because they are in fresh they actually produce MORE waste do to the way there physiology works... Monitor the tank very closely any signs of stress from him and do a HUGE water change. Also you may want to think about adding some salt to the tank, shouldnt bother the oscars at a tablespoon or so per 5 gallons but will help the ray.

Good luck!
 
I heard the florida stingray is born in fresh and throughout it's life goes from fresh to brackish and then from brackish to full salt. Those are the only freshwater ones in the store. What store did you get them from theres one that I know has them and keeps them freshwater when they are small?

Just an update. Can't get my phone to cancel out some of this light. There is some great maturity all levels stay below 10ppm. Fish fins, faces, and colors seem much better, keep in mind my camera is washing a lot of the color.CAM00271.jpgCAM00260.jpgCAM00259.jpgCAM00265.jpgCAM00269.jpgCAM00273.jpg

I'll keep all this in mind. Thanks for the very informative post.
