Angelfish?

Would it be ok to have a single black angel in a 20 gallon? Or is 30 the minimum? I wasn't sure because most people say the websites aren't always correct and the site i was looking at said 30 is the minimum. Also, I've had 5 cherry barbs in my tank for about a week and a half. Ammonia and nitrites are still at 0 but every once in awhile when i check the ammonia will be at about .25 but then within a few hours it will be 0. Is that normal? Sorry for this long post but another question! If my params are fine etc would it be safe to get a couple of blue rams or even a couple of ghost shrimp if i can't get an angel?

has your tank been fully set up and cycled for a week and a half? or did you just set it up a week and a half ago? if it's the latter, you are probably still cycling which would explain your ammonia jump. have you done a water change since you noticed the spike? has it changes sinced tuesday?

as far as your angel fish....IMPO, a 20G is too small for a angel fish, espically if it's a 20L...angelfish enjoy taller tanks

until you figure out if you're still cycling, I'd hold off on any fish for right now. someone else will jump in here with some advice too!

I had done a fishless cycle for nearly a full month before I added fish. Before I added fish I made sure ammonia and nitrites dropped to zero within 12 hours as well for 2 days in a row. How often should I be checking for ammonia in my tank?

hi
Angels fish would do well in a deep tank,
as long as your readings are stable and have been for a long time,then you could try
and keep some,once they pair off then any remainders should be removed.
i don't usually recomend angel fish to a new set up,as i feel IMHO they fair better
in a mature tank,however there are people who don't follow this and appear to not
have had problems.

Adding fish to a tank increases the bioload; in other words, each new fish is contributing more ammonia, which the nitrosomonas bacteria have to convert into nitrite, and then the nitrobacter bacteria have to convert the nitrite to nbitrate. As your tank is new, it may be cycled for what is in it (or was in it) then, but the bacteria have not increased sufficiently to handle the extra bioload. However, these bacteria multiply very fast by fission, each bacterium splitting to form two new ones, so as long as the fish are slowly added over a period of severl days to weeks, the system can handle it. Once an adequate bacteria population is established, the biological equilibrium is easily maintained provided there are no sudden overloads like too many fish, gross overfeeding, or dead fish not removed.

The usual cycle is 2-3 weeks under acceptable conditions, that is, not overloading the system at any time. If you add fish gradually you shouldn't have any problems. I would continue testing for ammonia eadch time something is added (the next day). I would only test the nitrite once, and if it is OK I would keep an eye on the ammonia from then on. If the amonia doesn't spike again, the nitrite won't either, as far as I undersatand things. The gradual increase in nitrosomonas will cause a gradual increase in nitrobacter. Just keep the bioload steady and gradually increase it.

Previous posts re the angels are good, and I would second the opinion that they are not good fish to be adding to new tanks. Angels can grow large and I would tend to agree with the earlier post that a 20 is a bit cramped. They also fare better with plants (they live among plants and roots in nature and thus feel more safe in such surroundings) and you haven't said if you have plants or not. Rams (Papiliochromis ramirezi) would be fine, perhaps with a few corys or shrimp on the bottom. All of these would appreciate hiding places, plants and bogwood being ideal. Angels and rams (and corys) prefer soft and slightly acidic water. What is your pH, both in the tank and from the tap?

I have Anachris, Java Fern, Java Moss and Anubias Nana growing in my tank at the moment. I was thinking about getting a couple of ghost shrimp for the bottom and a pair of rams as well. I just wanted to get an angelfish instead of the 2 rams, maybe a ram and an angel if i was able to, if not i'll just stick to the shrimp/rams and probably be finished. I just did my partial water change for the week earlier and my tank just read 6.6 and the water from the hose which i use since we have a water softener in the house looks like its at 7.6 or maybe a little higher. Also i just have a normal 20 gallon aqueon. no 20 long or anything special.

In that tank I would vote for the pair of rams, they are beautiful and will reward you with a spawning which is certainly fascinating to observe. Your tank pH is good for these fish and plants, very good. I read some posts about water softeners adding things to the water in order to soften it, sorry I can't remember if it was this forum or another, I belong to several and get mixed up. You might want to check into how your water softener works. The point in the other post if I remember it correctly was that the pH in the tank can suddenly change one way or the other, and of course you don't ever want that. Fish can adapt to slow changes over time, but not sudden shifts. Maybe start a new thread on water softeners and those who have experience can advise. I've fortunately never needed one as the water out of the tap is very soft and slightly acidic, ideal for SA fish.

Yeah i think the rams look great. When i go to the pet store should i just request a male and female? I think our water softener adds sodium to the water or something like that. my Grandfather just tells me it 'softens' the water and makes the soap in the shower sud easier haha. So yeah i should start a new thread. Also i've asked before but have gotten no answer...Out of my 5 cherry barbs the smallest one swims in circles or chills in the corner in the same side of the tank...is he intimidated by being small or something? Cause the rest are always either out swimming by themselves...or grouped up swimming radically back and forth through my bubble wall, they especially do it after water changes.

Not sure about the barb, your tank is still cycling and it may be that or something else. Fish usually respond positively to a water change, more evidence that it is a good thing and necessary.

On the rams, the male has slighty longer spines at the beginning of the dorsal fin (although in tank raised fish, which most seem to be now, this is not so obvious as it is in wild fish) and the female has a pink belly and will be a bit rounder. If your lfs is a proper aquarium store with knowledgeable staff they will know. If there are several in the tank, stand and watch them for several minutes and you will probably see that there are pairs; this is two fish (m & f) that tend to stay close, they will have the afore-mentioned differences, and the male will be driving others away if they get close. My lfs had a tank of rams the other day and watching them I spotted 4 or 5 pairs. If you see this, buy those two fish as they have already "paired' and will settle down nicely. But let your tank settle a bit more, it is still early and rams are not the easiest fish if things aren't just right. They are much more likely to survive if the tank is well established biologically; I'd recommend 6-8 weeks after you first put in fish.

I would certainly start that thread about water softeners if I were you; adding sodium to the water may be what was mentioned in the messages I saw a while ago somewhere. I'm pretty sure this does something to the buffering capacity, but I'm not a chemist. To be safe I'd want to know, and there are members here that understand this better than I do.

Alright, Ever since I've got the barbs they've loved to swim back and forth through the bubbles so i hope they're ok and not retarded or something. I've had fish in the tank for about 2 weeks now after the 4 week cycle.
