Help
I have been eagle eying this site for a while looking at the forums but I figured that I should finally post something
Also by the by...FANTASTIC WEBSITE!!! Bar none on these particular fish and members present!!! I also provided some pics of the tank and fish just to give you guys an idea (camara sucks sorry 
)Moving on now with my questions!Well I just purchased a 5" silver arowana for my 180 gallon fish tank (72" x 24" x 24")...Dont worry this is just his grow out tank!
But anyways I have had him for approximatly a good week or two and I want to make sure I am doing everything correctly. My tank is 180 gallons (72" x 24" x 24") run by a rena XP4 cannister filter. Inside the filter is 1 basket of Sponge, 2 baskets of Ehiem substrat pro, and 1 basket of bio chem zorb and fine filter floss. I do a 30% water change and gravel syphon every 2 days...keeps the tank crystal clear and keeps paramiters down! Parameters are as follows: Temp: 80 F Ammonia-0 ppm, Nitrite-0 ppm, Nitrate-5.0 ppm. P.H. is nasty here (very close to 9) so I use an r/o unit for our water. water is mixed with 3 parts r/o water and 1 part tap water with an appropriate amount of prime which maintains the PH at 7.5 not great but STABLE!!! Lights is one 36" coralife fixture with 1 x 10 000K T5 Sunlight lamp and 1 x colour max 21 T5 lamp. Lights are on from 8 am to 10 pm (12 hours). I have a couple live plants in the tank to maintain water quality including duckweed for drawing out the nitrites+nitrates, muting the light, and comfort for the fish!
To start off with diet...my little guy takes everything that hits the water surface!
But it works on a rotating schedule. He is fed twice a day (which will change when he is about 2-3 years old!) but morning feedings are alternating with one day being seafood (mussels, squid, clam, calimarhi, and prawns) and the next day being gut loaded de-headed mealworms and live crickets both gut loaded before hand with a mixture of carrots and hikari fish food. I will not feed feeders!!! and every night he gets a feeding of de-frosted hikari krill (for diet and colour!). Pellets are hikari food sticks which are provided when im in a rush (very little) or every couple of days I will put a couple of soaked pellets inside the seafood (just for dietary roundness). The best brand of food we have over here is hikari...so thats what he gets!So far is it all sounding good? Or should I be doing something else? Please tell me everything else I may have missed? But my guy has a few torn fins (not fin rot) but from the place I got him from...but I am just wondering if I should be using anything to help him re grow his fins or is it just a waiting game. I do not like chemicals (I run all my fish tanks all O-Natural!
) so I would perfer to let it grow back on its own if I have too! And also one last thing...I add about 2 handfulls of aquarium salt once a week (on sunday) to help with any bacteria or disease that wants to try and rear its ugly head! I have salt so I understand that salt doesnt evaporate, and that is why when the tank needs a top off it gets done and that the salt only gets added after a few water changes.So I would just like a little guide on dosing! But sorry about the long post I just really wanted to give you guys a good breakdown of how it is all going so I hope for the most thurough awnsers back But he really seems to be colouring up and growing nicely! Me and the aro really appriciate it guys (and gals of course! ) thanks a million and happy fishing!!! Attached File(s)
