Angels Depressed?



Some of you may have seen my recent posts regarding my Angel fish who have recently had their 3rd brood which was the most successful yet.

Ok, so we transferred them into their own 3ft tank in readiness for their next spawn hoping that being on their own we would have success with breeding. Well, it took them a few days to settle into their new home and realise that they were alone. However, they seem depressed. Their behaviour is nothing like it was in the community tank. They are still feeding well however they seem to spend most of their time hiding behind the big Anubias.

Tonight we have just noticed a white lump on our male, located just above his right eye. We are unsure as to whether this is an injury sustained perhaps on a fairly sharp rock or, something else. As a precaution I have treated the water with 'Aqua Septic' (I added 4 corys from lfs and 2 snails from our other tank). Usually I would treat the water whenever I add any new fish but this time I was wary as I was concerned I may negatively affect the next spawn which should be due any day now.

What should we do? Leave them and watch closely to see if their behaviour changes or, put them back into the community tank and accept the fact that if they continue to spawn their eggs/fry will be eaten but, they will be happier having their 'friends' around them?

It may be the reaction to being moved; some fish appear to adjust well to being moved to a new tank/environment, others do not like it at all.

A water change with slightly cooler water sometimes stimulates fish to spawn. And prior to that, feeding a good diet of live (if possible--brine shrimp, worms, insect larvae) or frozen foods.

Commercially-raised angel fish (as opposed to wild caught) generally fail with the first several attempts at spawning. They will often eat the eggs for no apparent reason; or if they do hatch, suddenly they eat the fry. I have read from experienced breeders that it can take several attempts before they seem to settle down and do the job properly. So don't be discouraged if the next few attempts go wrong.

As always, thanks for the helpful advice Byron. This morning we have cleaned the filter and Anubias leaves as there was a build up of 'muck' on the leaves and in the filter. Water checked and all parameters good. water temp good.

Fed some bloodworm which they always enjoy and guess we will just watch them for a few more days. We are not too intent on having them breed, we only moved them as they had displayed such wonderful parenting qualities most particularly with their most recent brood making it to free swimming stage.

Corys are happy in this tank and look extra cute with the black substrate making them stand out.

Am considering purchasing external canister filters for all my tanks and I feel not only will it be better for the water quality it will also make maintenance easier. What are your thoughts on this anyone?

A good canister filter (rated for the tank size) is good filtration for planted tanks and tanks with "forest fish" as I call them. You can adjust the water flow a bit to keep it minimal, or more if there are fish requiring more flow. The basic principle of design/operation is similar on all canisters, but they do it a bit differently depending upon brand. Can go into this more later.

What filters do you now have? And are the tanks planted?

Our 'Display Tank' 6ft, is full of Java Fern as it grows like wildfire however, due to having 3 full grown male Silver Dollars nothing else has really ever survived in this tank. We have an Eheim External Canister Filter on this tank which we find outstanding!

The Angels new home is 3ft and has a huge Anubias which we transferred over from the display tank with the Angels as this is where they choose to lay their eggs. We also have an enormous Java Fern in there which 'balances' the tank well. Currently we only have an internal filter which is adequate however, I find the external canister filters much less work and they seem to do a better job.

Our final tank is a 2ft which is home to breeding Mystery Snails and breeding Guppies. They have an internal filter which is sufficient, a small amount of Java Fern and another smaller type of Anubias attached to a nice smaller (than display tank) piece of Anubias. This seems to provide a nice 'nook' for the Guppy fry to survive being eaten.

As a side note, we have 11 clutches of Mystery Snail eggs currently. We watched in awe last night as we witnessed for the first time a clutch hatching. My, what a privelidge it was to watch. We have watched the snails laying their clutches but never before have we been so blessed as to witness them hatching! I am now beginning to wonder what we are going to do with 11 clutches worth of Mystery Snails?! Given the ridiculous prices the lfs charge for these babies, I may investigate selling them. Alternately they will be used as a source of food and entertainment for our Clown Loaches.

I should try and get some pics of our set-ups if anyone is interested!?

I have Eheim canisters on my 90g and 70g tanks, and they've been running now for about 15 years without a problem. Eheim are very well made, and are not only superb filters but have the track record to justify their higher cost. I honestly don't think you can do better than Eheim. I also have a Rena XP3 on my 115g, and I like the filter; it has not been around long enough to compare durability with Eheim, so while it is less expensive, over time it may not be if it needs replacing or repair.

For the two smaller tanks you mention, a canister or sponge on the 3-feet and a sponge on the 2-foot would be my preference. On the 3-foot you could go with an internal "sponge" type, I have an Eheim internal sponge, it is just a single sponge with a small motor and the unit hangs in one corner; they don't make these anymore, but another member recently mentioned that Fluval (I think it was Fluval) make something very similar. I like this unit because you have everything together and it takes up no more space than a dual sponge that would have to be connected to an air pump. Air pumps are certainly more noise than the other, so if that is an issue where your tank is placed, something to consider.
