The large aquarium matures

It is two and a half months since the large 250L aquarium arrived and was set up. It has matured and is home to a variety of well established aquatic plants, my mature male Bristlenose Catfish, one solitary Otocinclus and a shoal of colourful male Guppies. Unfortunately it has become home to some uninvited guests also. I have a nuisance snail infestation despite dipping all the new aquatic plants in bleach solution prior to adding them. I also have an algae bloom that has resulted in green water. Most experts would tell you that both are a result of overfeeding.

After repeated regular water changes ranging from a quarter to a third and almost half the water being changed at any one time the algae is still present. I have finally decided a little more intervention is required and purchased an additional internal filter and green water treatment online today. I have been removing the snails by hand several times a day and will probably use some kind of green vegetable to entice them to group and assist in their removal.

I love the new larger aquarium and it was a real bargain price given it’s size, however the filter that was supplied with it is not adequate nor functioning very well. The pump struggles to pump the water far enough up into the spray bar in the hood filtration system. I have never had a problem with green water in any of my other aquariums before and believe that the internal filters simply take the particles out of the water. I have had nuisance hair algae stifling my aquatic plants on the odd occasion though.

I have not introduced any new fish stock to my aquariums as I have been using one of my 60L tanks as water change feeder for the larger aquarium. I treat the water to get rid of the chloramine with water conditioner then allow the water to stand for at least 48 hours before adding it. This tank would be used as the quarantine tank for any new fish purchased as the other 60L tank is housing all of my Platys, Emperor Tetras and most of my Guppies.

I have not used my 20L breeding tank since the loss of my remaining pair of Neon Tetras. I would love to replace these fish along with the Otocinclus I have lost but need to cycle and establish a quarantine tank well in advance. This is my intention once the algae bloom in the large tank has been dealt with effectively.

The good news is that there has been some interest in the surplus Guppies and Platys that I have bred and wish to sell. Should I succeed in selling some it shall free up more space for a larger variety of occupants. It has always been my plan to have more algae eaters and tetras.

Should I get all four aquariums operational and cycled again, I shall have more control over the prolific breeders. The large aquarium for example is only inhabited by males therefore the tank will never become home to fry at present. Separating the genders will work to control the live bearers but will take some time as pregnant females can continue to have broods without males present. Having a separate fry tank can allow me to segregate pregnant females so they are not again fertilized by maturing offspring.

At present my 60L community aquarium has both genders of all three species it is home to and developing Guppy and Platy fry. It is my intention to leave only the pregnant females in this tank and move all of the male occupants to the larger tank. This is because the smaller 60L tank makes the removal of the young fry much easier and they can be raised in a separate tank.

So this is my latest update, there haven’t been very many in the last couple of months as I have pretty much left my tanks alone other than the occasional filter clean and water change. I blame the loss of my Neon Tetras on too much interference from myself and have learned from this mistake. There are still times though when some maintenance and intervention is unavoidable.
