Hi and welcome to the forum
Any idea what species the rubber lip pleco is?
What are the tank dimensions (length x width x height)?
What is the GH
(general hardness), KH
(carbonate hardness) and pH of your water supply?
This information can usually be obtained from your water supply company's website or by telephoning them. If they can't help you, take a glass full of tap water to the local pet shop and get them to test it for you. Write the results down (in numbers) when they do the tests. And ask them what the results are in (eg: ppm
, dGH, or something else).
Ramshorn snails can breed out of control and become a pest species. Netrites might breed but the babies won't survive. Sometimes their eggs don't hatch and you get white things everywhere.
Avoid dwarf gouramis (Colisa lalius) and all its colour forms (cobalt blue, flame, etc). These fish are regularly infected with the Gourami iridovirus and or Fish Tuberculosis, neither of which can be treated and once the disease/s are in the tank, they remain there until you disinfect everything. There are plenty of other small gouramis that aren't normally infected, so maybe look at them instead.
Buying 2 blue rams and putting them together doesn't always get you a pair. Rams like to choose their own partners and the best way to get a breeding pr is to put 8-10 fish in a tank and let them pr off naturally. Then move the pairs into their own tanks. If you can't do this, look for 2 fish that are staying next to each other in the tank.
