RTF: ... The RTC now called "Otto" will NOT eat pellets, and I cannot bring myself to not offer something else which at the moment is prawn plus 2 mandatory pellets which are still where I placed them in the morning
TBTB: Only hunger will motivate it to explore new feeds.
RTF: ATM Colony is nitrifying bacteria in a bottle.
TBTB: There is no ready filter in any bottle. AFAIK, all products of this type do is provide the seeding. It still takes time for the bacteria to establish, grow, and start processing the ammonia and nitrite. With a tiny bioload, perhaps a week could do it. With a large bioload, 3-5 weeks might still be needed.
RTF: Was watching a video on Youtube called 7 small fish which grow really big, and interestingly he didn't mention my two? he mentions Silver Dollars which I have kept in the past and they didn't grow very big at all
TBTB: "Really big" is relative. SDs are not big on my scale in 4500 gal. They are really big for an average home aquarium of 20 gal, that's agreeable.
RTF: ... also mentions a 'Gar'' which I had never heard of anybody got one?
TBTB: Plenty. Go to Forums page, scroll down to Advanced Aquaria discussions, find Ancient Fish, subsection Gars and Bowfins.
RTF: ...I already have the API test kits and I tested the water before the new Aro arrived it tested at Ammonia 0 Nitrite0 nitrate 20
TBTB: Excellent. Treat nitrate test as a relative test. 20 ppm on nitrate test can vary wildly from water to water. It is not an absolute test by any stretch like ammonia and nitrite are.
RTF: I thought the nitrate would have been lower as I had just done a water change, that"s the downside of having no substrate and no ornaments there is nothing for the bacteria to coat just the glass.
TBTB: that's why you have the filter and the biomedia in it. Denitrifying bacteria are anaerobic and live deep in substrate where there is no oxygen. They are not the nitrifying type that "coates everything".
RTF: Regarding the Arrowana being strictly a surface feeder, well mine isn't several times I have caught him coming to the bottom and picking up some prawn.
TBTB: Mine do the same. Arowana is not a strict surface feeder but a surface dweller.
RTF: ... also came up with an idea for decorating the tanks and giving somewhere other than bare glass for bacteria to coat. I'm going to silicone A long strip of black filter foam on the back of the tanks (inside obviously) foam will be 4cm thick and 4" wide along the strip I shall put some small slits and inside the slits I am going to put some aquatic plants, the foam will hold a considerable amount of nitrifying bacteria and the plants which will root into the foam will take care of some of the nitrate, just hope the fish don't eat the plants, is that a good idea?
TBTB: I think it's a good idea so long the fish are small. As they grow, they might damage or remove the plants with or without any purpose, especially the RTC.
RTF: ... also hoping that the foam doesn't take too long to arrive I had to order it from China...
TBTB: Make sure it is compatible with a fish tank and nothing toxic leaches out into the water.
