Are Bristlenose Plecos sensitive

Are Bristlenose Placeos sensitive in a new tank? Last week I bought 2 Bristlenose Pleco, 2 Albino angelfishes and 2 Siamese Algae eaters. One Place died. Today I bought another one and it seems to have disappeared. These Placos aren't anywhere close to their bigger cousins and immortal Siamese when in terms of being hardy.
 
I have kept them in the past. and they are more intolerant regarding tank maturity and oxygen availability. If you are having issues, they are the areas I would initially investigate.
 
Being hardy and being hardy in a new tank are two different things imo. In general ancistris are pretty hardy especially the multi generation tank bred ones but a new tank is always a stability challenge. It sounds like you added a decent bioload in one go, which is going to confound the problem, unless the tank is large. I'd suggest letting the tank catch up before even considering adding anything else. I don't add any algae eaters until the tank has began to show signs of algae and it's generally been left with only plants for 8 weeks or so before that becomes a consideration. I know we are in a modern world where every influencer stocks the tank on day one but patience is the best thing to learn and will lead to a much tank in the long run.
 
Hi all,

first and foremost, ancistrus (Bristlenose Plecos) prefer and need oxygen-rich water. As little organic polution as possible. If they come up for air at the surface, this is an emergency reaction. They don't like it! They are generally very resilient, but also susceptible to bacterial infections in poor husbandry conditions. Last but not least, they don`t really like unmatured '"baby" tanks. It goes without saying that they need sufficient hiding places.
If there are several ancistrus males in the tank, a clear hierarchy can be observed. There is always only one alpha male in the tank. However, lower-ranking ancistrus males occasionally try to see if they can somehow become number one. And the stronger one wins.

My tank Is heavily planted, more plants will come and cover every portion of the soil. That should provide plenty of space for fishes to hide and release fresh oxygen. And then there is river rocks and caves. I am a nature lover. I would hate even considering a non planted tank.

Is this for your 37L tank? If so, SAE and Ancistrus become too big, and you tried to introduce too many fish at the same time into such a small tank.

Also, you have been asking a lot of questions, about CO2, diatoms, angelfish (also too big) and Betta etc. can I suggest that yiu start a journal? Benefits of a journal are that everything is in one place and people, get a fuller picture of your tank and are then much better placed to offer advice and guidance to your questions,

I'd guess that is where we are.

Hi all,
First of all, your tank looks good. But it is still very underdeveloped biologically.
Once again about your Pleco. Make sure the water surface is constantly moving and leave out the CO2. Don't buy any more fish. It is always a sad sight to pull a dead fish out of the tank. And this may happen if you add more fish to this tank. This tank is currently more than fully stocked. And one pleco is more than enough.
There is a word that not all aquarists like to hear: patience. This word is the key to a good result.
 
Stop buying livestock. This has been the consistent advice on a number of your posts from a number of people. I am understanding when people have an issue because they have dived in without prior research but then reach out for advice. But come on, this keeps happening. Return the livestock, let the plants grow in (it isn't heavily planted, despite what you keep attesting), let the tank(s) establish, then research what livestock is suitable (post questions on here, many will be happy to help). Some may disagree with my tone but I think you are being tone deaf, repeatedly.

Where is the option of creating journal in this forums and what are the rules?

I have a big tank with dimensions 24 X 18 X 18. So if don't count the capacity of canister filter, it can hold 89 Litres of water, Once I get my next paycheck I will buy its cabinet and will start aquascaping it. Long before those Siamese algae eaters and Angel fishes reach adulthood, that tank will be ready and cycled.

I also have a 55 gallon tank which I am going to re scape in less than 6 months. So some of these fishes will eventually move in that tank.

You are on a forum that really wants to help you so creating a journal is the right path. You will get a lot of help if you take us through what you are thinking, so we can give you good advice.

You are also on a forum that wants to promote healthy livestock. Sone of the images you have posted and questions you have asked leaves us to doubt your experience. Don’t take offence - but I have not seen Angels with such maroon gills. I am an over-stocker but find your methods contradictory to health. It’s all too random for good fish-keeping.

Start a journal - it is 100% your best option to tap into untold experience.

Before moving to a journal this will be my last response in this thread. Yes I am still new into the world of aquascape. 2 months into aquascape and 5 months ago I had my first aquarium, that time I didn’t know anything about aquascape. So still have to learn a lot.

If you take a look at the pictures, I took these pictures from an aquarium shop. That guy kept a pair of angel in a tank slightly smaller than mine and those fishes looked happy so I thought my tank will be sufficient for a pair of baby angels.

The angel fishes that I kept in my tank are albino angelfish they have red head. When I brought those fishes home I too was shocked to see their gills having maroon color I thought it was some internal injury. I posted a separate thread for it.

Next day I went to the fish shop from where I bought these angels and she showed me that 80% of angels in his tank that are for sale have that maroon color in their gills.

1. The guy with the angelfish is being idiotic. 2. I had a bristlenose in a 100L and on reflection the tank felt small. We know that you know you will have a larger tank ready in the future. Stop buying fish until you do, and return those which are too large. You will always be able to buy them again. A big tank is NOT 24 X 18 X 18! It feels like you are trying to buy centrepiece fish when you have no space for them. The enjoyment in the hobby comes from evolving slowly, learning, and it is best to begin with small hardy fish.

Honestly try and <"find another shop">, that is a "shop-keeper with fish", not a <"fish-keeper with a shop">.

If you went to the garage and said "one wheel has fallen off my car" and the garage owner said "nothing to worry about, most of the cars I sell are missing a wheel" you wouldn't go back, and this is no different as a scenario.

The lovely people on this forum have no economic incentive to give you bad advice, so consider what they say to be in the best interest of you and your fish.

After working in a lfs I have dealt with hundreds of new fish keepers and the main theme for most is to much to fast. The ones that last in the hobby, normally the ones that avoid major disasters, are the ones who learn patience and the idea that research is better than throwing what you like in straight away. This isn't meant as a criticism just a word of warning that to really enjoy the hobby it's better to procrastinate in the beginning until you have more experience. We have all been novice aquarist.
