The white sounds like fungus. You were doubtful about having a pair, maybe the female laid eggs but there was no male to fertilize them. Angels and discus will do this, I'm not sure about rams.
yeah maybe that was what happened. do rams just lay eggs like this even when there is no male to fertilize? it seems like it would be evolutionary inefficient to spend those resources on eggs that would not hatch. oh well at least i know they are mature. ill wait for the other rams to catch up in terms of size and maybe they will have pair offs.
on another note, i called my LFS to order golden pencilfish for my tank, a school of them. they just called me back and they said that they dont have any golden ones but they have the coral red pencilfish (they called them red arc pencilfish) for 10 dollars a piece. at other aquariums, its 20 per fish so i know the price is good. i have seen the coral reds in planted tanks in a store about an hour from me. will the coral red (nannostomus mortenthaleri) pencilfish be able to do in a community tank? i read that the golden ones are good community fish. i dont know much about the coral red ones though. and for 10 dollars a piece it is tepmting but i dont want to kill any fish by jumping into a buy too quickly.

You lucked out on this. The Golden pencil, Nannostomus beckfordi, is not a particularly peaceful fish. It is quite boistrous, and can get nippy to slow fish or surface fish like hatchets. I have this species in my 90g with the more active fish and it is fine, but not in with sedate fish.

Nannostomus mortenthaleri is a beauty. I have a group in my 33g and they are spawning regularly, and without my intervention a few fry do survive. I have two mature fry at the moment. A real gem. Must have soft acidic water. Unless there is a breeder supplying the store, they will be wild caught, and this is the season for them. They are always expensive, and get at least six. Here's my 33g which is a good aquascape for them, they live among branches and bogwood in dimly-lit streams, the Rio Nanay is their habitat in Peru. Check the profile for more.

geez i guess i did. i read the profile and it said that the golden variety was one of the best for community aquariums. ok i guess there is a reason the LFS didnt stock them. i really like the look of N. mortenthaleri after i first saw it in a store down south a week ago. i will probably start with 6 and if they work then maybe up to 10 or so? either way it goes, 60 to 100 dollars is a very steep price to pay for fish that might not survive. but i guess since i already paid 30 for the woodcats, im already a victim of some rare fish-purchasing illness ;) is there a way i could acclimate them to harder neutral-ish water? or would it be better to try to slowly change the water in my tank to soft water?

also, i just noticed that when my platy was removed my rams a lot more timid. right now its just them and the cats in the tank. would a lack of dither fish cause this? there should be some hopefully tomorrow or next week but the rams hiding in the plants or behind driftwood, could it be caused by lack of dither fish?

I will revise that profile to make it a bit clearer. N. beckfordi is a good community fish, as it is not as "delicate" as pencilfish generally, but its feistiness does have to be born in mind.

If you decide on N. mortenthaleri I would get 7 and leave it at that. However, this fish must have soft acidic water, it simply will not last otherwise.

On the rams, yes, you are correct. Most dwarf cichlids can be very shy and having other fish around them (dither fish) usually settles them. But don't jump into things, you want to carefully select tankmates.

Just thought of something else, you have warm water for the rams, 82F or so, and the Golden Pencil is not too good this warm. All water parameters have to be checked for a species, GH, pH and temperature.

ok ill wait on ordering those fish til later. for now im going to order more hatchetfish for now. i have a few that i moved over yesterday so the rams came out a little more. they are doing fine today.
as for water parameters, im going to order a test kit online through amazon as it is cheaper that way, along with other things that i think i may need. right now my temp is about 81-82 so it fits with the fish im trying to purchase. im not sure my exact pH but according to the water report its neutral to basic. and since the rams were local, they grew up in these water conditinos as well.
on another note, i noticed some brown algae spots on my tank wall. right now i am running light from about 11-12 in the afternoon til about 9-10 at night. about a 10 or 11 hour cycle. should i reduce this to limit the algae? im also thinking about getting otos for this tank. i have 1 in my other tank (had 3 before) and he is very efficient.

so i was thinking about the acid/soft water needed for these pencilfish and i saw some products at the fish store designed to reduce pH, not straight pH but more of a buffer which i assume is better. they were by seachem and it was a neutral, acid, and basic buffer (3 different ones). are these products safe to use/have you used them before? as they are buffers, my first thought is that they are ok, provided that the fish have enough time to adapt to the change. in my last tank i tried using straight pH reducer but that did not work well. water has 0 buffer capacity so it hovered for a while, then plummeted. thank god no fish were in there at the time.

The brown "algae" is actually diatoms. In new tanks it is common to have this at some point during the first couple of months. As the tank's biology establishes this will disappear (not be increasing I mean). For now, keep it off plant leaves, it easily comes off with your fingers. And it will easily come off tank glass with a sponge scraper. At this stage it is not related to the light, but simply a fact of biological instability.

Bevfore you go down the road of adjusting water parameters, do a thorough bit of research. It is very involved, and dumping chemicals into the tank usually won't work, and these are very stressful on fish. If water has to be adjusted, doing it a natural way is the only safe way. As you say, the pH reducer didn't work in your other tank, and this is probably because of the KH (carbonate hardness or Alkalinity) which buffers the pH to keep it where it is. Have a read of this article:
http://www.tropicalfishkeeping.com/f...quarium-73276/

Then find out the GH and KH of your tap water from the water supply people, they may have this on a website. And test the pH of the tap water (shake a jar of water very briskly for several moments before testing to outgas the CO2).

ok i see. i just looked up my water quality report. the most recent one was from 2010 so not too recent now i guess. im ordering a test kit online (the freshwater master test kit by API as well as the GH KH kit by them too). ill order tomorrow and test when i get it.
as of 2010, the water quality was
TDS average: 95ppm, range of 27-174ppm
hardness (CaCO3) average: 53ppm, range of 8-104ppm
alkalinity (CaCO3) average: 49ppm, range of 8-98ppm
pH average: 8.5, range of 8.2-8.7
calcium average: 12ppm, range of 2-26ppm
magnesium average: 4.6ppm, range of 0.3-9ppm

from these numbers and your sticky, i guess that my water is soft? but yet it has a high pH. ill have real number within a week hopefully.
in the meantime, i was wondering. i have a few rams in the tank and they all get along. there are not many dither fish so they hide a lot but forage when the aquarium lights go out but my room lights are still on. some rams are larger than others. eventually, will they all reach the same size? or will some be stunted?
